The video comes with a caveat - but with the seriousness of Gordon Hayward's devastating ankle injury, we expect some.
The very-encouraging part is that he is full-tilt 1-on-1 and gets the dunk on the move with coverage. The caveat can be found in the tweet below.
Good to see progress, but he was elevating off of his right there. If he was elevating with his left (the leg he hurt), then I'd be fully in hype city
It does appear that Gordon elevates off the right leg, still favoring the previously-injured left one.
