His offense surely is raw but you got to give him 30 minutes to develop it. He literally owned the boards today and that was against as good a big man line-up as he will see in the NBA. He wasn't giving ground to Marc Gasol either, and that guy is as strong as they come. He also was catching some fairly difficult passes and getting his hands on richochets off the rim that were anything but easy to handle. I think you might be underestimating what he can bring this year.
I remember an interview with Ty talking about playing Gobert versus Brook Lopez (I think), where Ty said that if you put him in a situation like that against someone with that type of strength, will just demoralize Gobert. What a difference a year makes.
