Seems odd to be thinking about the final 53 when it isn't even May yet but that is what happens after the draft. Here is my best assessment.
By my estimation there are 47 players that will be on the roster for sure. The number is more important than the names but I wanted to show who I was counting:
5 Receivers: Fitzgerald, Boldin, Breaston, Urban, Doucet
4 TE: Spach, Becht, Patrick, Pope
3 QB: Warner, Leinart, St Pierre
8OL: L. Brown, E. Brown, Lutui, Keith, Sendlein, Wells, Gandy, Vallejo
4 RB: Hightower, Wright, Wells, Kreider (notice I did not include Castille),
6DL: Dockett, Robinson, Watson, Branch, Campbell, Iwebema
2 ILB: Dansby, Hayes
4 OLB: Berry, C. Brown, Okeafar, Haggans
4 Corners: DRC, McFadden, Toler, R. Brown
4 Safetys: Wilson, Lewis, Johnson, Rolle
3 ST: Rackers, Leach, Graham
2 more ILB as depth (Highsmith, Togafau, Hobson or whoever)= 49
Back up Center= 50
1 more DL (Maybe Dykes) =51
That leaves you 2 spots.
Do you keep one of the two return specialists we brought in? Do you add Long or Morey as receiver? Do you keep W. Davis as OLB? Do you keep H. Johnson? Do you include Castille? Or do you keep an extra corner or safety?
I think that Francisco, Ware, and Adams are all gone. But suppose you could keep one of the three which would it be?
If I were to keep 1 of these 3 I would keep Francisco. Adams is ok as corner but he is really a special teams player. Francisco is a better special teams player. Ware plays safety well but he is not strong in open field tackles where Francisco does better. Many note that Francisco does not do well covering burners deep. I agree. If he is on the field, I put him up closer and allow Johnson to play deep. Others note that he lost the Super Bowl because he blew his assignments. If you watch the game again you see it wasn't Francisco who blew the coverage. He was actually coming to try and help others. DRC and R. Brown were out of position in a couple of the zone coverage break downs in the last few minutes. Francisco did not blow any of his assignments in those last 2 minutes.
That said I am sure we will spend the summer rehashing over and over various options for the final 53 so let the fun begin:-)
