Tobias reminds me so much of Marques Johnson as a great mid-range shooter and an explosive driver to the hoop. He is also a determined defender and a very good rebounder. I don't see how he can't be a future all star for the Bucks given the opportunity to play on a regular basis.
I like Mbah a Moute in a defensive stopper role for the Bucks, but he doesn't have near the upside as Harris - especially offensively.
Harris is going to especially help Jennings and Ellis because he is going to be that important third player that can create his own shot and shoot at a high percentage while reducing the number of poor percentage shots that Ellis and Jennings have to take to carry the offensive load. The Bucks need to think to the future and hand Tobias the starting position as the new face of the Bucks. Mbah a Moute can still come off the bench to matchup vs. tough offensive players and shut them down.
