Tyler is certianly one of the best freshmen I have seen in a while. He does most of this while being double teamed as well.
For your sake, I hope you are joking. By this logic, every great player in history would have done better had he not been the best player on his own team. Maybe Scottie Pippen was way better than MJ. If you are the "go to guy" you take far more shots. He'd be scoring more, not less.
