Loved watching those videos with the Guard Whisperer. Castle is not messin' around. Growth is always non-linear, but, when things start to click offensively for him, he will be elite. It will probably build over a 3-4 seasons/off-seasons. Similar to the Shai trajectory.
I'll admit that I noticed that Vassell has not worked with him and I had the idea that Wemby could benefit from some of that focus on fundamentals, efficiency, ball-handling, etc. Harper will likely do some tune-up work with him next summer, too.
Lastly, I wonder how much it costs to work with that guy and his team like Castle was doing?
