It looks to me that there are 5 bubble spots where the battle is to make the final roster.  Barring injuries (except for Davis), here's how I see it. 

Locks (40)

QB  Moore, Clausen

RB  Dwill, Jstew, Fiametta, Sutton

TE   Barnidge, King, Rosario

WR  Smith, LaFell, Edwards, Wright

OL   Gross, Wharton, Kalil, Robinson, Otah, Schwartz, Bernadeau

DL   Brayton, Johnson, Hardy, Brown, Leaonard, Tyler, Johnson

LB   Beast, Connor, Anderson, Williams, Norwood,

DB  Gamble, Marshall, Munnerlyn, Godfrey, Martin

Spec  Kasay, Baker, Jansen

Probables (8)

QB  Cantwell

RB    Goodson

WR   Jarrett, Moore

LB   Culberson, Senn

DB   Pugh, Hudson

My Bubble Picks (5)

DT  Irvin, Landri

DB  Witherspoon, Francisco

OL  Pettiti

Heavy on DT and DB, but looking at special teams, and I like DT by committee to keep em all fresh.

Could use a better kickoff specialist to replace Carter, which would replace another Bubble Guy

.

Practice Squad Potential

RB  Vaughn,

WR  Gettis, Guy

DB   McClain, Stanford

DL  Moore

Of course, much can change and I might even change my mind.  I welcome your comments
