The final day of Senior Bowl practice is in the books, and despite it being a short one, there is plenty to glean from Thursday's activities down in Mobile, AL.

With notable players from the first two days, like Quinyon Mitchell, Taliese Fuaga, Taylor Guyton, and Jackson Powers-Johnson, sitting out of competitive periods, plenty of other players stepped up and filled the void left by the absent early-round prospects.

If you missed our coverage of the first two days of the Senior Bowl, just click on this link. Here are observations from Day 3 of Senior Bowl practice.

No Issue Finding Defensive Backs to Like

The WR/DB one-on-ones in the National practice got heated. With Brenden Rice making plenty of big plays, Oregon cornerback Khyree Jackson responded with a big day in his own right, and he let everyone know about it.

While talking trash is far from his best attribute, it is easy to love the fiery temperament the former PAC 12 defensive back plays with on the field. At 6-foot-3 and 204 pounds, Jackson has the size and length to be physical in press-man coverage. This was on display during one-on-one drills.

On one rep, Jackson jammed Rice at the line of scrimmage, throwing the former USC receiver off his route, which led to a misplaced ball. A few plays later, Jackson broke up a pass in the corner of the end zone against North Carolina receiver Quintez Walker. And then in a red zone period, Jackson blanketed Luke McCaffrey, driving the Rice receiver to the boundary, leading to an incomplete.

Jackson was only a one-year starter at Oregon, recording three interceptions and seven pass breakups last year. It seems his best ball is still ahead of him. He would be an intriguing perimeter corner for the Packers to target on Day 2 of the draft.

Rutgers defensive back Max Melton, brother of Bo Melton, also had a strong day, and he is another physical outside corner to keep an eye on in the draft for the Packers.

In the American practice, Auburn's Nehemiah Pickett capped off a strong week with several nice pass breakups in both one-on-ones and the red zone period. He's another long-armed six-foot cornerback, but he is a bit thinner than his peers, weighing in at 188 pounds. He could be a potential Day 3 target for Green Bay.

Underrated RB and LB Class

Unfortunately, two positions of need for the Packers going into the draft lack major star power in the early rounds. There aren't a lot of sure-fire running back or linebacker prospects this year--they all come with their fair share of question marks. However, the strengths of these two groups may just align perfectly with where Green Bay typically addresses these positions.

Tailbacks Marshawn Lloyd, Cody Schrader, and Dylan Laube continued to build on their strong weeks in Thursday's practice, showcasing their ability to win in space as pass catchers, while also looking physical in the run game during red zone periods. Add in Ray Davis out of Kentucky, South Dakota State's Isaiah Davis, and TCU's Emani Bailey, who have all flashed playmaking ability, and the depth of this halfback class is beginning to come together.

While some of the top running backs may not come off the board until the middle of Day 2 of the draft, this second tier of runners have starting-quality ability and could be taken in the fourth or fifth rounds. The Packers could draft two of these guys on Day 3 and develop them next year behind Aaron Jones.

Ironically, the linebacker position is fighting a similar perception. While many deem the class to be weak because it lacks top-end talent, there is a slew of solid mid-round players, starting with Senior Bowl standouts Payton Wilson, JD Bertrand, Cedric Gray, and Marist Liufau. All four linebackers practiced on the National team this week, which looked significantly better than the American team's linebacking corps.

While I already highlighted this group in my Day 1 and 2 recap, they continued to impress on Thursday. It's hard not to notice them. All four play intelligently, swarm to the ball, and have the physical tools to start in the NFL. They each held their own, as well, in coverage, which is a tall task when matched up against running backs and tight ends in space in one-on-one drills.

One linebacker I really liked on the American squad this week was former Miami safety James Williams. While playing around 215 in college, he's bulked up to 230 pounds to make the position switch in the NFL. He's played fast and looks athletic. As a former defensive back, he already has a leg up as a coverage player from his peers. However, what has stood out is his ability to read run progressions and close on ball carriers, while lining up in the box.

The Battle in the Trenches Continues

The offensive and defensive linemen have headlined the Senior Bowl practices, and with some of the big names sitting out of the competitive periods on Thursday, a few other names emerged as guys to watch in the draft.

Christian Haynes has put together a few strong practices, and while I mentioned him in yesterday's recap as a right guard prospect, he lined up primarily at center on Day 3 and looked outstanding, both in one-on-ones and the team period. While playing primarily guard at UConn, Haynes shows position versatility as an interior offensive lineman.

At 6-foot-2 and 314 pounds and 34-inch arms, he's not the stoutest lineman, but he's strong for his size and shows quick feet and great hand placement. He went undefeated in one-on-ones on Wednesday and Thursday. Currently, many project him to be a mid-round draft pick.

Texas tackle Christian Jones was another lineman who stood out in the American team's practice. After having a strong first day, he struggled a bit on Wednesday. However, he quickly rebounded and put on a show on Thursday in one-on-ones. He put to good use his 84-inch wingspan and 6-foot-5, 314-pound frame. Moving smoothly out of his stance, Jones locked on defenders, using his long arms to get his hands on defenders' chests, stopping them in their tracks.

In the team period, Jones showed great tenacity and lateral movement in the run game as a right tackle. He also didn't give up any pressures. There has been very little buzz about him when discussing the top prospects in this very strong offensive tackle class. However, he could be someone who could surprise people and go earlier than projected. He certainly has many of the physical and athletic tools the Packers value in their offensive lineman.

Interior offensive linemen Isaiah Adams from Illinois and Florida's Kingsley Eguakun had nice days for the National team, especially in the team period. They would both be nice pickups on Day 3 of the draft.

On the defensive side of the ball, Darius Robinson continued building on his stellar performance in Mobile, while Penn State edge rusher Adisa Isaac dominated the team period on Thursday. He won with speed off the edge on several reps, pressuring the quarterback. He would have had a handful of sacks if there would have been contact allowed on the quarterback.

Alabama's Chris Baswell made his presence known in both one-on-ones and the team period, after having a quiet first two days. The 6-foot-3, 260-pound Baltimore native fits the mold of what the Packers typically like in their edge rushers. He has tremendous burst and athleticism and could provide Green Bay's front with some depth on the edge.

Two former SEC interior defensive linemen, McKinnley Jackson out of Texas A&M and Alabama's Justin Egoigbe, also had nice days and were very disruptive in the red zone team period. Jackson is a stout 6-foot-2, 331-pound run defender, while Egoigbe is a gap-penetrating three-technique that wins with great hand placement and quickness at the line of scrimmage.

Is an Embarrassment of Riches a Bad Thing?

It's hard to go the entire Senior Bowl week and not mention the pass catchers. I know, I know . . . Green Bay is already set at wide receiver and tight end. I mean, it would be crazy for them to draft another pass catcher this spring. Right?

However, if a guy they love is available in a spot with great value, would you really complain if they added another dynamic weapon to their offense?

Wide receivers Brenden Rice, Malachi Corley, Jamari Thrash, and Ladd McConkey have all had terrific weeks, and if one of them were still on the board in the fourth or fifth round, it might be tempting for the Packers to pull the trigger.

At the Senior Bowl, Rice has shown crisp route running and physicality at the catch point. He uses his 6-foot-2, 212-pound frame well to muscle the ball away from defenders. Corley is a dynamic runner with the ball in his hands, but he has shown at the Senior Bowl better route-running prowess than many expected. He's also a real weapon as a returner, which Green Bay may need if they let Keisean Nixon walk in free agency.

McConkey and Thrash are both a bit too thin to fit the Packers prototype, but their polished route running and impressive concentration have been eye-popping down in Mobile. They are shifty athletes and a nightmare to guard in space.

Perhaps, there's a better case to be made for drafting a tight end. Theo Johnson out of Penn State has looked impressive as a pass catcher, and at 6-foot-6 and 257 pounds, he also fits the mold as a traditional in-line tight end who can block in the running game. He would be a nice addition to develop behind Luke Musgrave and Tucker Kraft.

If Josiah Deguara departs in free agency, then the Packers could also go in a different direction and look for more of an H-Back type of tight end, like Kansas State's Ben Sinnott or Florida State's Jaheim Bell. They both showcased strong hands and route-running ability this week, but they also have the versatility to line up in the backfield as fullbacks or move in motion as wings.

Under the Radar Prospect

One guy who had a quietly good week is UTEP linebacker Tyrice Knight. While the linebacker group in the American practices was a bit underwhelming, Knight showed all of the tools to excel at the next level as a second-level defender.

He took on blocks and held his ground against the run, while also shooting gaps and meeting the tailback at the line of scrimmage. He's quick to process and close in on ball carriers. He also moves well laterally, and he demonstrated his athleticism in space when guarding running backs in one-on-one passing drills.

His hat was always around the ball in the team period, as well, which is a good sign that he has a knack for reading opposing offenses and not wasting steps to get to the ball. Not many are talking about the UTEP linebacker who led the Conference USA in tackles last year. However, if Knight tests out well at the NFL Combine, then he could be a real steal in the middle rounds of the draft.
