Not a bad choice. I've come around a bit on Justice, so I wouldn't be horribly upset if he were chosen, I suppose. Good athlete who should make the transition to a LT in the pros.
McCargo as a nose in a 3-4? I wouldn't want to see it. But, as a compliment to Triplett in a Tampa 2-style 4-3 front, we could do worse.
I like Watkins, especially if he could be acquired this late. A steal that would help us where we badly need it.
He could be there, and if he is, what a steal! A great athlete, and while he doesn't have the best size, he is a fairly solid run defender also. Nice.
Another good interior rusher who did well for himself @ the combine. I think I'd probably look for a 2 gap DT around here though, and if that's the case, I'd go after Jesse Mahelona of Tennessee or Johnny Jolly of Texas A&M.
No!!!
Some people think he could develop into a solid corner like McGee, I think he's what he is: a great athlete w/ marginal skills @ a number of positions. He may even be gone when this pick is up, but I'd look to draft him later even if I were looking to draft him.
I don't see Sims lasting past the 4th round, but if he does, he'd be a good pick here for many of the reasons you mentioned. Boothe, I believe, is more likely to be there and would be a nice late pick. Very raw, but has a wealth of potential.
Here's another late round gem. You must be a fan of Marty & Matt's Pro Draft Report site (one of my favorites: they have nailed some really good mid/late round finds lately). Martin looks to be a diamond in the rough.
If we are looking for a depth player @ RB, I think Robinson would be a nice late round find. To me, he has a lot more upside there than he does @ WR.
I highly doubt he'll be here in the 7th round. I would probably take a flyer on him though if he were.
