Actually, it seems the Harper angle might have some legs. The problem with these rumors is that you can't know for sure whether the other source is just repeating the original rumor.
I think there is little question that Alvin Sr. was sore that his son was not offered by UT. There were several UT legacies in the last couple of years that were not offered by Butch. Billy Williams son who played at Farragut is one that immediately comes to mind. Terry McDaniel (Isaiah) and JJ McCleskly (Jalen)also had sons who weren't offered. Wasn't there also a Lady Vol whose son played O-line?
I didn't hear a bunch of whining from those folks.
