Arguments can be made for or against any of the three. As Slimm pointed out, I trust Ross more then Ireland. If they go Irelands route he can't weasel out of responsibility. If they go with Ross the team becomes more modernized with the QB position being the focus of the offense. Boles is the compromise.It seems like he's not really being considered, which is a good thing.
What is surprising to me is that with the votes of confidence Ross has given Ireland, he doesn't seem to have a lot of confidence in him.
