I have a philosophy on QBs like McCarron.  You'll see it across the board with QBs from USC that come from Mater Dei HS and others as well.  They get all of the best training from ages 5 through 17 that they make it great on to the college level (e.g. Tebow, McCoy, Marinovich, Barkley, Leinart, etc).   Once the NFL hits, there is an elite aspect of the game that your God given talent needs to get you over the top.  That's way a lot of QBs tend to fizzle while the playmakers (Newton, Wilson, Roethlisberger) succeed in the NFL. 

 

.... I guess to summarize my concept above ... these rich kid QBs that get full time elite QB coaching at such a young age, tend to peak during college.  The exception would be the Mannings.
