Wade had a perfectly legal step back. Steve Javie even went on ESPN and said it was the incorrect call. If that's a travel, then we should have gone overtime with Pitt in 2011. LeBron is a philosophical debate - whether an illegal screen that isn't used is really an advantage. You can make the case it was a good call, but it was a soft one. My biggest beef is that on the very next possession, Hibbert commits a clear illegal screen at the top of the key (wasn't his fault - Hill made his cut too soon).and they ignored it.
The officials clearly blew the shot clock call, but the end of the third quarter was a huge swing for Indiana - a soft offensive foul on LeBron for shielding a guy reaching in, followed by ignoring Stephenson's leg kick on his three (a point of emphasis). I thought George got some very soft calls against him in the first half, so It isn't like Indiana had nothing to complain about.
On edit: just watching the replay, looks like Stephenson might not have made any contact on his leg kick and just basically flopped on hiw own, which would be a correct no call.
