Well you could sit them all the next 2 games, and then in 1st playoff game ,1st qtr, any one of them could get hurt or knocked out.
Same thing if you only play them a qtr in the next 2.
It is risky, but better to play them in a normal fashion, play to win, and just hope no one gets hurt.
If you have good bkup's . wouldnt hurt to pull certain players after 1 half.
Carr is a small player, and he takes risks, holds ball too long, and he got hurt, Mariota is skinny guy, and Dak is bigger and more
sturdy built.
