I may be a little late to the convo but I've warn them before. I broke my left wrist and my left arm got bent. It's still bent actually, so wearing a sleeve helps keep my arm straight and helps it from getting hurt.
Interesting thought/point/input. Thanks for your contribution bro and joining the convo.
But Burke hasn't hurt his arm? So what do you reckon is the reason he's wearing the sleeve 1 day and not the next?
