I'm going to take this as an actual question and not snarkiness. I'm probably, once again, being overly optimistic.
Fast twitch muscle fiber allows explosive body motions. It's what we think of when we talk about"explosive athletes" (which is different from Exploding Kittens).
They work together in different ways, but usually vertical leaping skill and fast 40 times go hand-in-hand. Why wouldn't it be the same with Cuffe?
If Cuffe actually possesses the highest vertical on the team, he is also probably the fastest runner. I tend to doubt both attributes after his injury, but he definitely was an elite athlete before getting injured.
You could see it on a couple dunk attempts, where he tried dunking from farther away than his current skills allowed. But you could see from Cuffe's surprise that he expected to be able to do that. Hopefully his athleticism fully recovers this year.
