Ok, let me say this once again.
1. You're apparently saying that they were genin moving that fast, that's what I said to.
2. You're saying that they improved so they can now move even faster, I agree.
3. Here's what I'm saying, they were genin, they moved at very fast speeds, now, the rest of the ninja that were their age are approximately as strong as anbu members, and Naruto's about as strong as a Kage.
4. So for said reasons, they are stronger than Lee and Sasuke when they were Genin. If you don't agree with that then... wow.
5. For reason number 4, they, or more than most of them at least, are indeed faster than them when they were genin.
6. They "teleported," as you say it, when they were genin. Meaning that the other ninja are able to "teleport" now.
Ok?
