There are several things I like in this swing. One is the walking away from the hands. It looks so smooth and natural. Just let the clip play and check it out.
Is this BP or HR derby? Also is he hitting off a mat? It's a fairly nice swing but it just does not look aggressive.
I don't see the missing frames/overlap.......
Absence of a tight HPP. Arm plunge instead......
The important stuff is not present in this particular swing.......
