As per the title. If you're still playing MyCAREER and/or its connected modes and you're still tweaking your jumpshot, give Brandon Ingram's animation a try.
Base: 75
Upper Release 1: 113
Upper Release 2: None
Blending: 0 (or 100% in favour of Upper Release 1; same thing)
Note that you'll need to have played enough of MyCAREER to unlock the Jumpshot Creator. Ingram's jumpshot must be created, as it's not a unique animation that you can just add and equip.
It works best with a Gold Quick Draw Badge (as Ingram himself has in the official roster), but even without it, it's a pretty good jumper for getting Greens and good releases. Ratings and Badges obviously still come into play, but it's a fairly easy animation to master. Speeding it up with Quick Draw should make it even more effective, especially online where a slower shot really opens you up to a close out and some cheap blocks.
I still like Klay Thompson's animation for my guard build (and his free throw animation for all builds), but Ingram's feels like it works better with my big man build. If you want to try out Klay's animation, his is a unique one that doesn't need to be created using other animations.
