When was the last time a slam dunk uncontested first overall pick went back to school and played another season when it wasn't mandatory? And don't give me that Sam Bradford crap either, because he was nowhere near a lock.
When was the last time we were in the CBA situation that we are now seeing?
The uncertainty of football next year will be HUGE factor in the decision of many underclassmen.
If the CBA were in place, I would say it would be 99.9% certain that Luck came out.
With the current situation, no one really knows.
