Terrence Ross has a pretty outrageous vertical, as you can see here. He's got time on a baseline dunk to do a quick pump. Quincy Acy recognizes this excellence and celebrates appropriately, as you can see above. Quincy Acy should celebrate all dunks.
UPDATE: No word on how Acy celebrated this second Ross dunk, but it was even more impressive. Hopefully, Acy celebrated in kind.
