I'm including ERFA, RFA, some UDFA, and Graham and De La Puente in this mock depth chart.

Leaving off the Secondary FA as it's not easy to predict who will stay or go. I also only included the current most likely UDFA but am leaving the rest off.

That's 52 of the 53 man roster(missing the starting or backup LT) going off the assumption everyone under contract stays(not likely) and before we add in 2014 FA and draft picks.

It could be drastically altered at a few positions given how things play out this year, particularly at WR, LT, RT, both OLB spots, and both S spots.

Cap casualties could also play a role, specifically with Greer, Robinson, Harper, Hawthorne, Chamberlain, and maybe Sproles or P. Thomas being the most likely.

Currently it has 24 spots for offense, 26 for defense, and 3 for special teams. Spots that could swing are:

QB up to 3(not likely)
WR down to 5(50/50)
TE down to 2(less than 50/50)
DE up to 5(less than 50/50)
NT up to 3(counting Johnson as a DE; greater than 50/50)
OLB down to 4(unlikely)
ILB down to 4(50/50)
S down to 4(50/50)

Traditionally we keep:
2 QB
4 or 5 HB(I think 4 is definitive for 2014 barring a draft pick)
1 FB
5 or 6 WR
3 TEs
1 C
1 C/G
2 G
4 T
5 CB
5 S

I won't list what we do traditionally at DE, NT, ILB, or OLB as the switch negates that. You usually have 2 deep at each spot with an extra lineman and an extra linebacker. Usually the extra guy or someone ahead of him is versatile enough to play 2 spots(DE/NT and ILB/OLB). So you're likely to see:

4 or 5 DE
2 or 3 NT
7 total linemen

4 or 5 OLB
4 or 5 ILB
9 total linebackers
