The kid also would have been much better off — if he really has NFL talent — playing in a top conference for someone other than his daddy.
That's why I typically focus just on their performance in games against ranked teams... the closest comparison that you can find for seeing how well they will do against NFL level talent.
Shadeur went 13-12 overall... in a lower conference... with a roster custom-built for him, by his own father, including the best athlete in the nation... and worst of all, Shadeur never once defeated a ranked team. (Week 1 #17 TCU finished that season at 5-7, clearly a ranking based on nothing.)
There is a significant list of Heisman Trophy winning QBs and NCAA Championship QBs that never got drafted... a 13-12 lower-conference QB who never beat anyone of NFL caliber talent? Yeah, I'm thinking no.
And it was GLORIOUS to watch an all-hype-no-substance figure, ranked as high as the #3 Draft prospect, get utterly humiliated by all 32 teams, 4 or more times each, and 144 times total.
