Minimum total requirement of 38 players. 18 Offense + 17 Defense + 3 Special Teams.
Remember only 45 (of the 53 on roster) suit up for the game, these will usually be
39. 4th safety
40. 4th DE
41. 3rd DT for 4-3 teams / 3rd ILB for 3-4 teams
42. 4th DT for 4-3 teams / OLB for 3-4 teams
43. your kick & punt returner
44. a 5th CB (or WR if 43. is a CB)
45. can be anyone, your 8th lineman, a kickoff specialist, special team standout, your third QB, a 4th RB, a 3rd TE, another DB, your 5th CB/WR etc...
This is the way NFL teams go, it barely changes from team to team. If it's in the game it's in the game, no?
