I'm with footey on Yabusele. He is different from Semi. He is far more fluid and obviously he is bigger. Yabusele uses his size with very good effect.
I think they both have solid shooting ability which explains why they're still on the roster. I have watched a lot of Yabusele from last year and he hasn't played in a league that offers anything resembling defense. Thus, I don't know about that end of the court for him. He might be the prototypical "small ball big" as he appears to have an above average motor, what the heck he is still a kid.
Semi can shoot and pass. He looks quite good on offense close to the rim. Again, SMU and SL weren't huge on defense, but, Semi plays square on his feet and runs the court well.
My concern for Semi is he is deep on the roster in a fairly crowded spot. He has not had any D league yet, thus, I think he will see time in Maine.
An overlooked rotation might feature a PF and center combo of "Semi and the dancing bear." They would punish small ball line ups wouldn't they? The T shirt sales are a potential bonanza.
Yabusele has had his so called professional year and "might" be able to run, pass, shoot and push his 270 pounds into some minutes.
