Malcolm Floyd v. Ari, has been in the 90's in yardage and scored a TD in each of last 2 weeks
Ryan Mathews v. Ari, appears as though he will get the start this week, Ari is 31st against the run
LT @ Buf, has taken over lead back role, Buf is 27th against the run and has given up league high 5 rush TDs through 3 weeks
Austin Collie @ Jax, all Collie has done is lead the league in catches, yardage, and receiving TDs. Jax is 29th vs the pass and has given up league high 7 pass TDs. Manning will likely eat them alive.
I'm leaning towards sitting Mathews down this week. Just coming back off the ankle injury, perhaps he goes and needs to be spelled more often this week.
