Yeah, LT had declining years in SD. But part of that is age. RBs have less tenure than other positions. They get banged up and retire by 32. Mathews is young, and against an undeniably terrible defense. You HAVE to start him. He's healthy again, and Rivers isn't going to have to throw. If you were looking for a breakout week for this rookie, of all weeks you'll get it this week. Start him. Even tho it's hard to bench MJD.
And of course start Bradshaw.
