People are so silly in their conclusions.
Is it surprising that QBs recruited for one system would leave (ala Tanner Lee) when the system changes? Attrition like that isn't even unusual when there's no upheaval.
TO QB recruits from '88-'91:
Bart James - never lettered
Mike Grant - 3 letters, but no honors
Marvin Callies - never lettered
Todd Gragnano - never lettered
Matt Jones - never lettered
Berringer - 4 letters and consummate great backup
Chester Johnson - 3 letters at receiver
Tony Veland - 3 letters at safety
It is amusing to watch people flail about this when the majority of them are the ones who have argued day in and day or that Riley needs time to get a QB for his system.
Classic example of uninformed critics latching onto random stat pulled out of thin air with zero context.
Confirmation bias rears its head again.
