Assuming his work ethic is exactly as advertised, Gobert is going to have a solid career. I don't know about all-star, but he'll be a player you want.
What struck me most is he's always active and moving about. His head is on a swivel on D watching for the ball and he's making alright use of his length to get boards. Once he learns solidly to box out, he'll be a monster in that area simply due to his ridiculous wing span.
He wasn't pushed about as much as much as I thought, but he could use some meat on his frame. This isn't as much of an issue to the evolving nature of the 5, but it'll due him well because he can use his weight to his advantage. I'm certain the Jazz have already setup a line at Sugarhouse BBQ and time slotted in the gym for him.
As noted, he's got a nice touch on his free throw shooting, which should translate well to a 15 ft. jimmy in time. Once he gets a few post up moves and is more comfortable with his back to the basket, he maybe very good player here.
To be frank, I don't know how he fell where he did honestly. For a prospect, I'm sold.
