I believe thats 49 right their, we should see competition at CB, DL and OL. I could see us carrying two TEs with a 6th RB if we keep the 4 RBs 1 FB and ST RB
If the current is 49 of the 53, we would IMO keep 2 other OL(OT and G/C), OLB and DB or TE. Dobbs and I.Williams spots aren't guaranteed right now, I think Tukuafu is, he was playing great before he got injured.
But all could change if we add a CB, OG, OLB, DE, NT, any one of those.
