Myles Mack is a hell of a player and I recently had the chance to thank him in person for playing at RU. His passing this year was a whole new facet to his game that was really enjoyable to watch.Nonetheless,if you look at the NBA their is only one successful player at his size, nate robinson.
On the Knicks we have Shane Larkin, and his size really limits his game. I think he'll play overseas but from what i hear, playing overseas can be pretty tough. He choose RU for a reason and that was to play d1 ball and to give his parents a chance to watch him. Regardless, he'll play somewhere. Probably overseas.
Kadeem Jack i could see ending up on a D league team somewhere. D league, overseas, and maybe one day in the NBA. He could use some weight to contend at that level.
Just my thoughts. I wish the best for both of them.
