I wouldn't mind getting Derek Harmon or Mykel Williams, though its a while since I drafted either in mock drafts.
My last mock (Draft Buzz) gave me these players in the first 6 rounds, all of whom I liked.

Trade with Giants - Packers 23rd pick for their 34 and 65.

34 WR Emeka Egbuka. still on the board - thank you, I'll take him.

54 DT Alfred Collins. Crazy strength. 320lbs 34 5/8" arms. Top notch run defender who can also walk linemen back into the QB with his power.

65 Edge Ashton Gillotte. Another very powerful and explosive guy. Elite testing numbers. Only available here due to short arms.

87 CB Darien Porter. A late developer with elite testing numbers, good height/weight (6'2", 200). High performer in man-press.

124 C Jared Wilson. 6'3", 310. Either the best or 2nd best Center in the draft. Super-athleticism shows up everywhere. Ideally, he needs a year to add strength and improve as a drive blocker. Fine in pass-pro.

159 RB Bhayshul Tuten. A light RB (5'9", 206) with lightning speed (4.32 40). Fun player to watch and great for the KR job and schemed touches.

198 LB Jamon Dumas-Johnson. 4.50 speed at 6'1", 238. Excellent speedy thumper who could be a core ST player and LB backup.

Andy, what exactly makes Harmon “fun”? Is it possible to talk about professional football like it’s professional and not pee-wee. Man up the takes a notch.

Going into the draft, I think our roster is looking like this:

McManus, Orzech, Whelan. (3)

Love, Willis, (2)
Jacobs, Williams, Brooks/Lloyd (3)
Kraft,Musgrave, Sims (3)
Reed, Doubs, Wicks, Hardman Melton. (5)
Walker, Banks, Jenkins, Rhyan, Tom, Morgan, Glover, Monk. (8)

That's 21 active guys on offense and the three special teams guys.

On Defense,

Gary, VanNess, Enagbare, Cox
Clark, Wyatt, Brooks, Wooden
Walker, Cooper, McDuffie, Hopper, Welch
McDuffie, Williams, Bullard, Anderson/Oladapo.
Nixon, Valentine, Hobbs, King.

For every rookie that makes the team, one of these guys won't.
