they are played sparingly. As an example, this happened to Corbin Kaufusi when he returned from his European mission. He was used on 3rd down plays, but Steve kept him out due to not being fully conditioned or ready.

HS speed due to Div 1 talent/experience/speed. You see it all the time. They are learning to adjust to a much faster game. Give them time, but out of the gate...I don't expect much, especially against P5 teams.
