I would have thought changes of speed are what average-good athletes use to keep elite athletes off balance.
If you're quick, changes of speed can be even more effective than if you're a plodder like Jingling. Change of speed keeps your opponent off-balance, and when you're fast / quick, it accentuates this. I also would disagree with your assessment of Mitchell's ability to penetrate. I think he is even better at it than Dante, who might have a quicker first step, but Mitchell seems to have a better cross-over and his strength enables him to ward off the contact better than Dante, kind of like Kyrie.
