Tatum has been a treat to watch so far. He is opportunistic and hasn't needed to use his ability to score in ISO situations very often.
To put things in perspective Tatum's offense is comparable to Otto Porter so far this season. Both are scoring at an elite efficiency with low usage rates. There are nearly 120 players that have a higher usage rate than Tatum yet he is still 50th in PPG. The sky is the limit!
