We're seeing multiple instances of Tyrod badgering Roman to get the call in so he can take it into the huddle. With those two backs and that defense, I know the Bills want to shorten the game, but there is a point of diminishing returns and they took a running leap beyond it last night.
The upside of Roman being so "measured" is that it works effectively toward keeping a green QB very calm and in control. But when it starts having a deleterious effect on real-time game conditions, I think it's definitely time to re-evaluate how you're doing things.
Personally I wish the guy would just write three different scripts and utilize two of them after the half.
