You just explained it perfectly with your statement. Let me add this, though. How many college football observers would have Roberson on their all time top twenty quarterbacks list? Outside of KSU fans, they answer may very well be none.
The answer is none, but I think he is the best quarterback of all-time at any level and he won us our Big 12 Championship, so I don't think any of these apply:flameouts, disappointments, defectors, "never lived up to the hype," and just plain SUCKED.
Sure his "actions" before the Fiesta Bowl truly felt like I had been stabbed in the heart and we lost the game because of it, but I have forgiven him and love him.
