Honestly I don't even know if I'd call Memphis an incredibly talented team after watching them. I'd call them an insanely long and athletic team. I didn't really even see their problem as figuring out how to play team offense. It looked to me like a roster full of guys that were extremely limited in terms of offensive skill.
I think this is something that if I was a basketball recruiting service I would try to address. Ranking a guy like Duren that high as a college recruit seems like a huge mistake. I absolutely don't see him being a great college player unless he stayed 3 years, which one way or the other probably isn't happening.
As far as college recruiting goes, bigs that are athletic but raw probably should not be ranked nearly as high as they are, as they are probably not going to have a big impact in the college game. By the time they put it together they are already going to be in the NBA or G-League.
