Read option

I read that Coach said the defensive performance this year kept him awake and that the read option/spread was troubling to him or something like that. I guess in practice he and the new DC will have to have a QB that can practice this for our new scheme to prepare for. The same way he has in the past brought in left handed QB's. Seeing it is a new/old wrinkle that may stick around, and he has said it is troubling for an offense to defend against, i guess this would be prudent on the team's part.
