It doesn't surprise me to see any of the pros using this stuff because of the kind of stress they go through. I've seen a ton of pros using it in their warmup.
Funny story with this...at cincy.
Joker was getting warmed up for his tuesday practice session and was using this stuff and the stretchy bands. After a while, he was warming up his shoulders and had the stuff anchored behind him when he pulled it forward, akin to a pelvic thrust basically. Some girl made a cat call from the crowd and he looked over and smiled while laughing a little.
Pretty funny stuff!
