I graduated in '77 and watched Bailey for 2 years and then sporadically thereafter. Bailey was definitely more of a polished product as a sophomore. That being said, in my view, Omoruyi is more athletic than Bailey ever was. He's quicker, jumps higher and, most importantly, he is a quick twitch jumper. In other words, in my view, there is no one that gets off the floor as quickly and as high as Omoruyi does. It's almost super human. If he gains another 20lbs of muscle and is able to maintain that elite athleticism with that added weight, the sky is the limit. I think he could become a 1st Round NBA pick -- but only if he's able to figure out how to shoot his one handed jump hook with his finger tips and with some arc/touch. That is one bad looking form he displays. I would think he could correct that, but he continues to "flat-line" that shot like 4 out of 5 times he shoots it.
As to the rest of his offensive game game, in my view, he actually looks better facing up and shooting the mid range or 3 pointer than you'd expect from such a raw offensive player. If we had another monster rebounder on the court with him at the same time, he could wind up being as good of an outside threat as -- say -- Kadeem Jack was. I don't see why he can't become that type of player too.
As for defense, he has a long way to go. Any center who is strong and good around the basket, has eaten him up this year. He consistently overplays the strong side of his opposition and does not react well (too slowly) when they spin in the opposite direction. This is typically true in the first half of games. In the 2nd half he seems to learn from his mistakes and adjusts. He's also improving as shot blocker. Not quite at the level of Hamady or Myles, but getting there.
