Just thinking out loud here, but wouldn't he have been a better choice for quarterbacks coach, at least compared to Nick Sheridan? Not knocking the hire since the man worked wonders at Plant and we have talent at WR, but it seems odd.
I suspect that he was brought first and foremost for potential recruiting impact. Also, there's nothing stopping him from helping to develop QBs -- don't think the delineations are as bright-lined as some think.
