This is an easy one to answer as Zeke, his mom and his stepdad all publicly stated that Zeke himself was responsible for his slower-than-hoped-for development, not the coaching staff. Zeke publicly stated that he really didn't develop a passion for basketball and a strong desire to play professionally until his senior season. He said he originally played basketball because his family expected it of him, and he started off at UA using his basketball scholarship just to get a degree. There's no way a coaching staff can develop a player to their full potential unless the player wants it for themselves. All the evidence needed to prove that Zeke developed slowly in his first three seasons and then took a big jump up in his senior season when he finally wanted it is shown in his stats and NBA scouting evaluations. As a senior he not only improved his defense to become the #3 shot blocker in the country, he also dramatically improved his offense to the level of top 10 nationally in shooting percentage and top 25 in player efficiency rating (PER). NBA Draft Express said it appeared that Zeke had turned the corner in his senior season to become a legitimate NBA draft possibility. But they cautioned that big questions remained about his laid-back demeanor and lack of toughness, which come from within. As I've said before, if you could have transplanted Tree's intensity and toughness into Zeke, Zeke would have been a first round NBA draft choice. Then again, an abundance of intensity and toughness with inadequate self-control can lead to an entirely different set of problems.
