He was terrible last season too. So, let's see if he improves this season. Carr had very similar numbers over his first 5 seasons compared to Watson. Both played on mostly subpar teams with good offenses and poor defenses. So Watson hasn't exactly outperformed Carr by much, if at all. The main difference is Watson can score with his feet. Carr can, but that's not where he shines.
