In the Hornets' defense, I remember him being basically the consensus #2 guy in everyone's rankings that year. That year was Anthony Davis and everyone else. It's easy to look back and see how guys like Lillard, Andre, Beal have panned out but everyone thought MKG was the guy at the time.
Today, MKG is a top defender and the Hornets are a totally different team with and without him. His jump shot is improving every year and he's definitely capable in transition. Plus the guy is what, 22? Yeah, he wasn't the best #2 overall, but I have a very hard time saying he's a bust.
