I don't think the fact that it's preseason needs to be clarified. It's common sense that the players don't play as hard in preseason, Gobert won't face starting front lines of Bass and Speights in the regular season, he won't average 20 & 10, and he won't shoot over 80% from the line. He will likely tire throughout the long NBA season as most players do, and will become a little more inconsistent with his newly formed skills as he becomes further removed from his meticulous summer reps, but he'll still end this season with a higher skill base than he ended with in the previous one. He will still be a relatively poor offensive player this season; however, it's painfully obvious that he has improved his offensive game. That's really all that needs to be said.
Well thanks Sherlock, since we are in the painfully obvious department, let me say that since the fact that it's preseason doesn't need to be clarified, I don't need to clarify either that nothing is painfully obvious in the NBA until it takes place in actual NBA games right ? Refrain from being condescending please, it's very possible the glimpses we have seen in those games don't stick during the season, just as it's perfectly possible too that there is a real improvement. The What is clear is that it is way too early to draw conclusions ont what is painfully obvious or not.
