Staying the course with Nembhard does have a clear purpose. The Cavs just drafted a first round wing who is not a great creator, but can get open off ball. They also want to see what they have in a rookie big who is a plus creator. That sounds like a recipe for running an offense with purposeful sets.
Nembhard knows the coaches and has sat in on Charge and Cavalier film sessions. They aren't developing Nembhard for a great NBA future... but they trust Nembhard to run a real offense which develops the other guys.
At least, that should be the goal. I watched a few summers as the guards played selfishly. Dion and Kay Felder both ball-hogged badly. Last year, Okoro never established himself as a play initiator. Hoping Nembhard puts Mobley and Ogbaji in good positions.
