When a disabled player exception (DPE) is granted, most NBA teams never use it. They let it expire. I doubt Danny Ainge would do that. I believe he will use it, even if he ends up signing the hotshot from the local YMCA. And nothing within the bounds of the NBA rules is out of the question for Danny. Even idle or retired players in their late 30's and early 40's. More on that in a minute or two.
The NBA All-Star game used to be a forum for trade discussions because it was scheduled prior to the trade deadline.
