Two thoughts about the OL. Darnold is more likely to be able to make plays when the OL fails. Bridgewater got hurt when nobody touched him. I would guess Darnold is more durable. Second thought if you want to keep Teddy B so Darnold doesn't get killed, I would be all for letting Bridgewater be the sacrificial lamb.
So far Bridgewater looks pretty good on the run. Anybody can have a fluke injury too but you're right Darnold has more of a build that looks like he could take a beating. I'm assuming the 4 extra years of life make Teddy a little smarter for playing behind a cruddy line but that's just an assumption, I don't know its true
I can name a quarterback who I'd like to see get killed behind a lousy offensive line but his name isn't Sam or Teddy and he's not on our team either????
