Pros for playing starters and getting the win:
1. Both times Bills starters had extended rest they came out flat the following week (Mia and Balt).
2. Losing 3 out of 4 going into the playoffs is a bad look. Not what good teams do.
3. 11 wins is a great milestone. Bills will get more respect in future. More prime time games possibly. More attractive for FAs possibly.
Cons
1. Starter could get hurt. How bad would that look?
2. Getting a back-up more playing time would be nice if needed in January. If JA went down in Houston I would feel a lot better if Barkley had a full game under his belt.
I think I agree with the HC. Play the game to get the win by playing the starters.
