I've had arm injuries before. I understand what he means by sometimes it worked, and sometimes it didn't, and that he kept hoping he could "play through it."
Sometimes you throw it just the same, with the same force, same intensity, same everything that you ALWAYS have.... and then the ball just doesn't go. You don't understand it, but it just DOESN'T happen.
I think Todd injured wasn't much worse than Burns in full glory.
Either way, I'm just glad he's got it all sorted out and is getting "better."
