He is, but the NBA got lucky that they didn't win that game after the refs completely screwed up that sequence at the end of reguation before he hit that first game tying three.
How does a ref who is standing in the perfect position to make the call not see that Rivers didn't even touch Lillard when he took that (first) shot? And then they go to the replay and "uphold" the call, except the call on the court was a foul on the shot and they decided to "uphold" the fact that Rivers hand lightly brushed up against Lillard while he was still dribbling. If THAT is the standard for a foul in the NBA there would be a foul called on literally more than 90% of all possessions, and by the time the game ended there would be no one left on either team to play the game. But after the refs looked at the replay and realized that they completely blew the call they didn't have the cajones to admit their error, so they just made something up.
That officiating was every bit as bad as Lillard's shot making was good. To use the phrase of another all time great, he's a bad man.
