TJ Leaf or OG Anunoby.
Depends on who we take at #3 or who we trade for. If we pick Isaac, then Anunoby becomes superfluous. Though I like the power and wingspan of Anunoby, he can cover positions 3-5 (which is rare) and is also a strong finisher in transition. His shot and the ability to create in the halfcourt is really questionable, but maybe he can develop that over time. He fits right in our attempt to become the best defensive team in the NBA.
Leaf on the other hand is mostly known for his great offense. His shooting stats are really spectacular. He's very creative and can be a post playmaker or play at the perimeter and be a threat with his passing, driving and shooting skills. But he will definetely need time to acclimatize to the NBA level. He needs to add weight to be a good rebounder like he was in the NCAA.
