Just to add on a couple of things...
-This is also a relatively new system that has drawn a handful of schools out of football obscurity. Wait a while for those now successful programs to start recruiting at a higher level and you'll eventually see more pro QBs. In the end, it's about talent and not system.
-If the system is holding kids back from making the leap to the pros, then how do we explain the fact that an increasing number of pro teams are adopting elements from the zone read offense?
I tend to defend the media quite often ... But that is a lazy question.
