100% agree. I think a lot of fans put way too much stock into the QB separation and 'but will he leave?' discussion. Virtually every recruiting reporter out there will tell you that a program's QB depth doesn't really matter much as someone might think. Most QB's are entering college believing they're the best and/or they're going to win the starting job. If they don't, and they want to start, they transfer. I think the coaches are incredibly aware of this and do their best to prepare for it.
In Smother's case, we might get a year out of him because of the redshirt rule. But, if McCaffrey or someone beats him out in 2021, somebody is likely going to transfer and it just is what it is.
