He will go up against Jack and Javin, yes because they will be playing on the 2nd squad often... But Zion NEEDS to go up against RJ who will play SF/PF... You will see RJ on the block a lot, and at some points he will be a small ball PF... I don't think the competition level has been overblown. I hope he can grow his gam over the summer playing competitively against RJ, Cam, Jack, Javin, Ques... RJ is a winner, a competitor... who will challenge Zion the Best. Zion should play more of a 4, but he will play a lot of the 3 as most players don't want to embrace playing on the interior. He needs to embrace playing closer to the basket.I think Zion is much more likely to go up against Javin and Jack Day to Day than he is RJ, since they are different positions. Also this idea that Zion has to adapt to the skill level and size as if he has never seen it before is being way over blown.
I say he needs to play RJ because RJ is the best player... the best competitor... That will make Zion Better. RJ is a 3 with ability to post and play some 4 and Zion is a 4 that will play a lot of 3...
