He will be the 15th player on the squad. He is 6' 10" so he has height, which the celtics need. What's not to like really.
He looks skinny so I don't know if he can box out, but he does jump well and has incredible timing.
Not sure he can play under the basket due to being thin, but he is worth a try. If he ,looks good in practice doc will give him some playing time.
Maybe he can be this season's steisma. I wish him luck.
