re: Deion and Shedeur Sanders playing the villain role well on Twitter

You're making up a narrative. Shedeur was under pressure to the point that it was stagnating the offense.
There was a legitimate chance to win against USC, but the offense slowed down too much. Watch the end of the game if you didn't see how it unfolded.
There were problems.
I don't think it's fair to put all the offensive line struggles on Lewis. But that is partly on him. He had input on personnel. The linemen that transferred from Kent State have since transferred out.
