One thing we obviously lacked this season was muscle inside. Roger did a good job, but he was too short for some situations. Corbyn Jackson might help that situation immediately - if he can play.
Oliver Black should definitely bring that to the table, too.
Oliver is extremely athletic, but from what I've seen, he's not bulky. He's a different type of player than Roger. He doesn't have Roger's ball skills and outside shooting ability from what little I've seen of him. He seems to be an around the basket player. I know absolutely nothing about this Jackson kid, other than he's large. Guess we'll find out in a few months. A new year always brings new excitement.
Che Bob is listed by Rivals as a power forward.
