PTAC deals with injured people all the time. I have as well. As a guy trying to deal with a bad back I get it. Sometimes no matter what you do it acts up and it is frustrating. Sometimes you also know it is on you. Backs are one reason I remain scared of Vaughn having issues. If all it took was running in the outfield over a couple months to have it go, he very well may have issues down the road, or as he ages, or at any f'ing time.
