I personally think Alex Len will be one of the biggest busts in this years draft. He hit just 38% on low post shot attempts, he was usually physically dominated by the defense, and he also had a great ability to completely disappear from a game consistently. He does have great body size to dominate defensively and is athletic but among the NBA Big men I don't see much of his game that will translate to the NBA. I see Len being a player who comes off the bench and can provide some energy defensively. But not much more than that. He's ineffective offensively, sometimes struggles rebounding, and does disappearing acts during games. If that happened during college then he's really going to struggle in the NBA.
