I fully agree with you that WR is a huge concern - and I'm in the camp that we've had back to back to back poor hires to coach that position. And Stubblefield may be a good guy but Miami fans weren't shedding any tears when he left their program, so this may be another stumble.
Quite certain that this hire was mostly KC decision. I don't think CJF would do it in a vacuum. We will have to trust that Kirk knows what he is doing. He left Matt Simon behind at UM so must think highly of Taylor.
