We already got rid of our soft bigs and upgraded almost every position. But every year, there is that guy who gets all the heck when they lose or not doing a task well on a consistent basis. Last season, it was in group of Olynyk and Zeller because of their inability to protect the rim.
Base on my observation from the preseason, Nader could be a prime candidate due to his ballhog tendencies. Yabu could get a whiplash too because he's too raw and will commit alot of rookie mistakes. We've also shown Semi's lack of court awareness at times and his passiveness.
