One day it will all make sense
Fair point and to answer your question only one I can recall is Tomczak.
while you were busting balls there are fans who think this matters. I mean, before Baker who was the best QB from Oklahaoma? Before Mahomes, had there been many successful QBs from Texas tech? Same for Allen/Wyoming, Brady/UM, Brees, Purdue (Griese, I guess), Rodgers/Cal, etc.
Really aren't any schools until the latest Oklahoma run I can think that were good at producing QBs.
To answer your question about BIG QBs, I'd add Cousins and Wilson off the top of my head.
So to recap...only Brees, Wilson, and Brady. Cousins...could throw Burrow in for that matter seeing as he graduated from OSU.
