I understand the strategy involved as you have listed and I agree that they need to maintain an active/inactives list for rotational purposes. Unless, as you said, they incorporate a DL, which would be abused and I don't see as a realistic option. My point, and maybe I didn't explain it thoroughly, is that if they increase the overall roster by 7 players, they should at least increase the active roster to the same degree. Maintaining the same number of inactives weekly at 8 as opposed to 15.
