So are the guys that left Penn State and Ole Miss after everything that's happened, quitters?
Did they leave mid-season... if so, then yes they are quitters.
Why does it matter if they left before or mid-season? A lot of these schools gaurantee four year scholarships now, so while not binding, they are committing to you and you are committing to them.
The Question was in regards to Penn State and Ole Miss NCAA Violations and penalties.... in which those kids did not know about prior to any commitment. If they left after the end of the season after the penalties had been levied, then I wouldn't consider them quitters. If they left mid-season before said sanctions when into place, I would consider them quitters.
In terms of KB leaving Clemson after 4 games... He knows every year that there will be a competition for the QB spot. He was never guaranteed the starting role. He left mid season after he lost the position. This may be a good thing for him (I don't hold it against him at all for leaving), but he is a quitter. Again, quitting is just an action... it could be good it could be bad. A lot has to do with what lens you're looking at it through. As I said prior, quitting smoking isn't a bad thing for the smoker, but it isn't so good for the tobacco company.
In regards to your 4 year scholarship comment, KB has essentially taken away a scholarship for this year that could have gone to someone else. So although I think he's actually making the correct decision for himself... he's screwing Clemson in the process. It is what it is, though.
