I understand what you're saying, but I don't necessarily agree with the categorization.
I do agree that this statement looks like he's using too much of the personal experiences coupled with the emotional side of being a college football in his decision making process. That's one statement. I don't know if it's an issue in all of his decisions or just as they relate to the quarterback room or just this one instance with Luke. I don't think it reads like he's feeling sorry for himself, rather empathizing with Luke. He's been there, done that. If it keeps the kid in LIncoln and gives him a chance to excel in the position.....or maybe potentially elsewhere, I'm fine with it.
Using your own experiences in your role as a leader is actually kind of required and he's still in the age range where the kids can see him as a former player, not just an old ball coach. If McCaffrey was to struggle for two more years, showing little or no improvement in the position and we see this same kind of statement from Frost, then I think he's got an issue. I still won't know if it's McCaffrey specific, QB specific or broader, but at that point the stance will be flawed.
