Hall's ability to face-off against in the open court against good Big12 PGs — daring them to risk a foul by reaching for the ball — that's really not something Jimmer woulda done. Not nearly as much of it as Hall does, anyways. Jimmer woulda been more cautious in the open court against that level of competition.
Granted, Jimmer would've had them at his mercy as a scoring threat pretty much from the time he crossed the halfcourt line. But that skill is of course only partly about ball handling.
