That's an interesting half-1st round mock, I find several points to be intriguing in there:
1) They have us taking Bush and our only other option they see is trading down, no Vince in there.
2) I don't think Greenway will go that high, he should be a good LB and the 49ers will likely need one since three of their four starters are free agents, but I still don't see him going that high, although they could trade down for him because apparently Nolan really likes him.
3) I find it interesting that they have the Browns taking Tamba Hali (I've seen similar picks for them a couple times). They mention the Browns DLine needs help, but they run a 3-4 and Hali is definitely not a 3-4 DLineman, he could make a good pass rushing OLB in a 3-4, but I think he's heavy enough right now that he'd be a better fit as a 4-3 DE. I think the Browns would definitely take Greenway if he's available, otherwise I could see them taking Manny Lawson as an OLB for their 3-4 or taking one of the DT prospects (Bunkley, Watson, etc.) or going for a DB.
4) I'm not sur eI see the Eagles going with Lawson, I think they could go WR (likely Santonio Holmes) or DT (again Bunkley or Watson) or maybe LB over getting a DE.
