BYU put more players into the NFL last year, but it's still a very small percentage of players.
Bronco thought about and talked about being booed in his first game as HC for YEARS after. If you don't think the criticism gets to them, you're simply wrong.
If people want to criticize players - whatever. But I wouldn't recommend the players go looking for it. And on CB they'll find criticism, whether they're looking for it or not.
