It's one thing to hold up a sign or yell things at a player to mess with their head. It's completely different thing to to taunt and provoke an athlete after having physical contact with them because they were making a play and ended up in the stands. Now I'm not saying in anyway that Smart shouldn't face consequences, because he should. He should have walked away. But fans can't expect to verbally and physically interact with an athlete in an extremely negative manner and not expect the athlete to react either verbally or physically. If a player comes into the stands, help them up and keep your mouth shut.
Seriously, what kind of jackass follows around a lousy bball team, sits behind the goal at home games, and develops a rep for taunting players? This isn't really a race issue, it's a lack of maturity by Smart, and just being a complete jackass by Orr.
