He showed no tendency in that direction through the game when Buchner was hurt. Seems like no.

In fairness to Buchner, I also feel like Rees through his play calling was not putting him in a position to succeed. I think he's Crist like in that he's an athletic kid, but he has bona fide accuracy issues and does not move through progressions one iota, but Rees seemed to expect that it all would "click" at some point for Buchner.
