DD's back flip change vs fast ball mechanics

[Kevin Burt Lasiter]

My novice eyes see her mechanics, getting open, good posture on her back flip are way better than her mechanics on her fastball. What do you guys see? She controls the backflip unusually well, compared to her fastball? Really strange. I have 2 videos attached, one fastball, and one back flip. Thanks in advance.

The only thing I notice is the lack of push off. It's almost like it's about to happen and then it just stopped. Overall both pitches looked similar which is good.

I would agree with CoachBroker. I don't see any drive off the rubber just stepping. The drive foot has no separation from the rubber until the stride foot lands near 9:00. A good drive will have separation near 3:00.

I found this video when she first started pitching. Does she look way better then than now?? Looks to be way more explosive then?
