I don't know anything about Kalu, but surely you know about the Boum finger, the Covid protocols, the Kennedy foot issue, the Verho back issue?
We could use another guy to distribute the fouls in the paint, but that's about all Kalu has been contributing. I think if he works hard he could be a solid player for us his Junior and senior seasons, but he's not a very important piece of the puzzle right now, IMO.
