I wonder how many spots are truly "open" on the 53, especially on offense?
If Kerridge sticks, which seems likely, Monty and Williams would seem locks at RB with maybe one other opening.
The o-line would seem set unless Patrick can somehow unseat Barclay (Amichia to PS).
QB is Rodgers and Hundley, with Callahan if they can swing a spot.
WR is Jordy, Ankles and Cobb, Janis and Davis would seem to have jobs to lose with Special Teams contributions, and Allison in week three would seem a strong possibility also, so maybe only one spot there, max, and two draft picks.
TE seems set with Bennett, Kendricks and Rodgers.
8 O-line, 2 FB, 3RB, 2QB, 6 WR, 3 TE is 24, with probably only one spot somewhere in there, saving three spots for the specialists.
On defense it's a little more open, maybe.
DL of Clark, Ringo, Lowry, Daniels, Jean-Francois and Adams would seem set. (6)
OLB of Matthews, Perry, Fackrell, Biegel and Elliott. (5)
ILB of Martinez, Ryan and Thomas (with Burnett and Jones with snaps) (3)
S of Burnett, Clinton-Dix, Jones, Brice (with Randall taking snaps if Rollins locks nickle corner down) (4)
CB of King, House, Rollins, Randall (4)
That's 22 with probable spots for at least two of some combination of Gunter/Goodson/Tripp, really only leaving 1-3 spots open.
Of course injuries may change this, especially if Montravious Adams or Biegel suffer setbacks.
