On this, or possibly other threads on this site about this subject, I have read several times that Podunk U did something just as bad to Elmer Fudd 20 years ago, so that makes it OK for Louisville today.  By taking that defense Louisville fans don't seem to know it, but they are screaming that what was done in this case was wrong.
The Louisville coaches admit they changed their minds, reneged, and gave the scholarship to someone else.  That's not even up for debate.  He didn't change his mind about anything.
You accept a job for $100,000 for the first year and when you show up for work you're told your pay will be $10,000.  You say no way, and they say you had a change of heart.  Not a change of heart to me.  You just got lucky and found out early that you were dealing with a bunch of (what ever you want to call them, but nothing good).
U of L definitely did "drop" him, sadly they (and the vast majority of their fans) just don't see anything wrong with what they did.  And repeatedly saying they didn't doesn't change those facts.  They reneged big time, and the representatives of the football program don't really deny it. 
Strange how things work out.  Now he gets to go to a "class" school.
I have no dog in this fight.   I had no respect for U of L to begin with.  I just like to brag when I am proven right, and my lack of respect is confirmed.
