The final 53 man roster is not set in stone yet, there will be a bur of tweaking over the next week or so.

Firstly I think there will likely be trades, in this case a LB and perhaps a WR (likely for future draft picks).
I think 9 LBs and perhaps 7 WRs is too many particularly when you will have 8 players inactive on game day.
I think it is a case of Reese wanting to make sure he gets value for these guys with talent, he isn't going to five them away.

There are a few positions the Giants will want to upgrade if the opportunity presenrs itself. I think they will ideally want to bring in another DB, perhaps a safety like Brian Pollard (Chiefs) or Courtney Greene (Seahawks) who will improve safety depth and provide a valuable special teams role.

Other positions that the Front office will look to upgrade if possible are #4 DE (Tollefsen), #5 DT (Douzable) and #3 TE (Johnson); in fact we are reportedly already bringing in TE Alex Smith (Pats/Bucs) for a visit, I think he would be a great fit for us.

Other guys we may be looking at include DE Tim Crowder (Broncos) and DT Shaun Smith (Lions/Browns)
we could also include trading for players (instad of picks), for example Chiefs DE Tamba Hali who is better as a 4-3 DE rather than a 3-4 OLB.

I guess my ideal roster moves would be

Trade LB Gerris Wilkinson for DE Tamba Hali (Chiefs)
Sign DT Shaun Smith
Sign SS Brian Pollard
Sign TE Alex Smith
release Derek Hagan/Tutan Reyes (probably Reyes)

that would give us a roster something like:

FB (1): Madison Hedgecock

WR (7): Domenik Hixon, Steve Smith, Mario Manningham, Sinorice Moss, Hakeem Nicks, Ramses Barden, Derek Hagan
