According to Shumpert, he can shut down pretty much anyone. Up to, and including Michael Jordan in his prime.
Yes, the same Michael Jordan who averaged 30 points per game over his entire career, and is widely regarded as the best player ever to step on a basketball court.
Shumpert's comments, from an interview with Steve Serby of the NY Post:
There’s only so much you can do when somebody hits jumpshots with three people’s hands in his face ... but I probably would have denied him better than anybody else. As far as just not letting him the touch the ball, I probably just wouldn’t let him touch it. Even though that’s hard enough, I think I could have kept him uncomfortable. I wouldn’t have backed down, it’d been me and John Starks in his face if I had been on the Knicks back then.
For some reason, no matter how many accolades Shumpert piles up in his career, I don't see Jordan ever even wasting his breath talking to Shumpert about something like this. But hey... a guy can dream, I suppose.
