The problem is, it's a QB centric system that doesn't develop QB's and often forces them to do things they're not good at.
Every QB that's played at ND since 2010 has gotten worse the more they played. Even Ian Book struggled with indecisiveness and not seeing guys wide open in 2020. His playmaking ability, once the called play broke down, is what bailed ND out again and again that year. Deshone Kizer had no clue what he was supposed to be doing with the ball half the time in 2016. Did he all of a sudden become a talentless ass clown? You give Urban Meyer a Brandon Wimbush and he's a Heisman trophy candidate just like Tim Tebow, because his coach doesn't force him to do things he's not good at and doesn't give two shits about his throwing mechanics.
QB talent is not, nor has it been the problem since 2010. There have been kids with a fraction of the talent ND QB's have had playing great football every Saturday since 2010. They've just had better coaches that know how to utilize their assets while minimizing their faults. With BK and now TR, it's just install the system, run the system. QB struggles with touch passes? Doesn't matter, keep calling plays that require the QB putting touch on the ball because that's what the system demands.
If TR/BK had Aaron Rodgers at ND he would be a terrible QB and some of you would be screaming for the more talented back-up.
I should qualify this by saying that talent was a problem when TR was QB.
