Agree he is blocked, but I think in the regular season you want to limit minutes for Brook (34 years old) and Serge (32 years old), and I think that is his current value. The Bucks have every intention of winning the title, so will need to have their 30+ year old big men somewhat rested and ready to go after the 82 game season.
Then, with continued development, the following year I think he can get playoff minutes.
