I look at it as a learning process. Just even getting a private workout with a team is GREAT experience and helps prepare you for the workout that will really count down the road.
Think of it like a job interview. The more practice at it you get, the better you'll be when the perfect job comes along. So going through the process can only help a young man be more comfortable in next year's process and so on.
Plus, Nick is more athletic than some of our fans give him credit for. He runs great for a big, FT shooting is improved (always a n upside for post players). What he needs more than anything is to learn to play defense with his feet, not his hands. And that alone would get him more minutes on the floor, which would help him offensively.
I'm betting he has 1/3 of the years of bb instruction as most of his peers. I'm still shocked we haven't heard of him spending a summer at a big man camp. Would do him worlds of good.
