Several weeks ago there was an ESPN commentary on expanding the roster for Thursday Night Football, perhaps directly activating the practice squad specifically for depth and preparation. This principal underlines the strategy behind an 18-game schedule in which players may only suit for 16 games. Assuming that the 53-man roster will still be the acceptable standard on any given Sunday, simple math would argue that increasing the rosters to 60 players – in other words full activation of the practice roster – would allow for a perfect rotation over the course of a season.
However, this sort of Euclidian geometric solution does not account for roster realities such as injuries, midseason signings, and ensuring appropriate depth at all positions, something which this theory would hopefully be based around. For these reasons, rosters would likely be expanded to a proposed 65-man capacity. If the extra five would remain in a role similar to the current practice squad or if they would be on game-to-game activation is something that would have to be looked at further.
