I remember when we had Matt Ryan at BC, we were running a pro style offense (which has pretty much been the case since the Tom Coughlin days), which led to Ryan having a relatively smooth transition to the NFL despite Atlanta being consistently shitty.
Dearth doesn't mean what you think it means. But I agree with your point. I honestly think these big programs best asset in developing QBs might be the aspect of having constant media attention, especially in a market like NYC or something.Take Alabama, for example. With the dearth of talent they always have at WR, RB, and OL, you don't have to be a Josh Allen, Alex Smith, or Patrick Mahomes to shine.
