First, TRob is definitely not a shot-blocker right now, and I do think that by and large you either have shot-blocking instincts or you don't.
I want to mention that I've been watching a lot more of his Kansas games and wanted to note something that I've been seeing in regards to weak-side shotblocking.
In watching him play, it looks as if he doesn't even attempt to block shots from the weakside even when he has position and an angle to do so. Instead, I'm seeing him position himself on the weakside for a potential defensive rebound.
I'm seeing very little shot-blocking potential from him, and I don't think he'll ever be a shot-blocking force...but I wonder if he has been coached that it's better to position yourself for a defensive rebound rather than lose defensive rebounding position going after a shot-block.
I have no idea, but wanted to throw this out there. So who knows, maybe if he's asked to sacrifice defensive rebounding position in favor of more aggressive shot-blocking, we might see a bit more from him in that department. Don't think he'll ever be elite at it, but if asked, could provide some additional rim protection that we didn't see while he was at Kansas.
I also want to mention that pairing him up with Cousins and JT might leave the team lacking in paint intimidation, but at least it's a physical front-line which can own the boards. If we had just drafted Bargnani then I'd be really frustrated with that front-court, but Robinson brings physicality and athleticism that you want from the PF position.
Keep in mind that he was also paired with one of the best shotblockers in the NCAA last year. There's a possibility that Self told him not to worry about blocks (which would help explain how he only got .2 more blocks a game despiite playing twice as many minutes as the year before) and be a better man defender.
