It's not going away. I'm sure Kalani doesn't use it when recruiting against him, but I'm sure a number of people have and will always not just bring up what was proven, but the other allegations that were never resolved because it was he said/he said. It would almost be irresponsible for a coach of a competing school not to bring it up as something to consider.
That being said, if you're around the game enough, he's definitely not alone in saying what he said(proven) and saying what he was accused of(not proven). It doesn't make it right, but a lot of guys grow up around it in HS and college and that's just the norm. The fact that you're painting him as some sort of victim for being able to be penalized to the tune of only making half a mil to coach a game for a year is pretty funny. Even funnier that he'll be making 10x that because he muscled through it. I'd say he made an educated decision to let the chips fall where they landed and is probably a better man today because he got caught doing in a culture what often occurs in that culture.
