I have a comment and suggestion for the simple roll Turner does from a forward-facing position. Basically, the roll he does is not going to save his knees. I've looked in slow-motion and he seems to do a no-handed flip onto his upper back, and then continue to do an okay roll. To truly save yourself from injury, you need a completely circular motion engaging the whole body, including the arms. Here is the man with the best roll I have ever seen:
I know you guys are busy, and this is not exactly priority stuff here, but if you plan on rethinking the roll animation in the future hope this helps
