well let's think about it this way:
miami will take Long thats almost given because they have ronnie brown and can't take McFadden (like how houston took Mario instead of Bush because of Davis). Also they won't take Ryan because Parcels is smarter than that
Rams could go OL but i really think they will go with Dorsey because the only problem with their OL last year was injury. While they might go with OT Long to make that line a little younger, their defense was too bad to not spend the number 2 overall pick on.
With Dorsey gone, Falcons will take either McFadden (to fill stands in the absence of Vick) or Ryan. I think that the Falcons will go with Ryan because he would be better to rebuild their franchise around. McFadden is not the complete prospect that Peterson was at RB and thus will not be taken by the Falcons.
With Dorsey gone, Raiders will take McFadden because we all know Al Davis' pension for drafting freaks at their position.
Now the chiefs are the X factor for the patriots. If they draft Jake Long, which I think they will do, Pats should trade down because of the depth of the CB position in this draft. However, if the chiefs go CB Pats will be forced to take a CB because by the time their pick comes around in round 2 a lot of good corners will be off the board. Even if the Rams take Jake Long, Dorsey will be off the board (going to ATL), McFadden will still go to the Raiders, Ryan won't be a consideration for any team before the pats, and the Chiefs will most likely take Clady. So Pats won't have an OT to draft.
Considering Dorsey and McFadden will most certainly be off the board when the Jets get to pick they are going to take Gholston. I hate to say that but I think no matter what happens in picks 1-5, Jets are taking Gholston.
All this considered, Pats could go with a CB but I don't think they will. If Ryan is gone they can trade down with The Ravens and then Trade down again. If he's on the board, Ravens will not trade down because they know we won't take Ryan. In that case, we could trade down with the Saints so they can have their first choice CB. Either way Pats could trade down again.
So to answer the original question. Gholson will be gone, Rivers does not fit our system and Ellis would be a stupid pick considering Wilfork.
Best case we somehow land Gholston because McFadden somehow falls past the Raiders and Falcons and is taken by the Jets.
Realistically, I see the pats trading down, Taking the best available corner in the middle or bottom of the 1st and coming back around in the second and taking an OLB/DE in the second round. THis would hopefully be Groves. He's not as strong as Gholston but he is certainly faster.
