At barely 6', if you get in Mayfield's vision he becomes a different QB. He's not Russell Wilson.
2nd, as good as I think he's going to be in time, he doesn't have a very effective Oline and he can be fooled by disguising coverages.
He has some nice skill position players. But the team is not playing as a unit; more as a bunch of individuals each wanting to be featured on a high light reel.
As horrible as the Jets are, they were always starting from about their own 15 yard line. So when the Browns got the ball they were always starting from their own 40. And still the Browns had trouble moving the ball and scoring.
Sure, the "on any given Sunday" rule always applies. But the Rams ought to beat Cleveland handily. That it's in Cleveland doesn't matter; Rams are a good road team.
