I'll just throw this out there..... I know it could be too early for OC and this is assuming he would leave the booth so soon but I would love to get Romo in as QB coach and eventually be OC. I know that sounds homerish but I think Romo has a better grasp of the modern game than most. He damn sure knows how to scheme and call for adjustments, as has been made evident by his exceptional calls in the booth. I guess the other hang up would be having him work to develop his replacement, and who knows how much he actually likes/respects JG. But I'd rather get him before another team does. One of the best football minds in recent history.
Also I think Romo helped Dak and Linehan more than we realize last year.
