I think he might be willing to make the changes now but if he came in as QB coach first he still may have done the exact same thing Doman tried to do and reinvent the wheel...

However, he would have done slightly better IMO. We have no shortage of potential OCs after Grimes moves on. The question is, will they command the same respect Grimes does?

A good Coordinator is often viewed as a jerk, because they are obsessed with effort and exactness.
