That's where those that have a disdain or dislike for Rees are wrong. It wasn't his fault he was thrust into the starting QB role at ND. Blame BK for that. Rees was simply a scholarship player who happened to get the nod by the HC and OC. Blame the coaching staff for not recruiting better.
As for becoming OC at ND, again the HC made the decision to hire Rees, so to have any type of dislike or disdain for Rees is ridiculous.
Let's put it this way, Put yourself in Rees' shoes. HC tells you, you are QB1, are you going to say sorry coach, I don't think I am, give it to someone else?
Same for the OC position, HC extends you an offer to be OC of ND, are you going to say, sorry coach, I don't believe I'm ready? 😂 no one on this forum would do that unless you are complete loser.
