SIXERS: 76ers Trade Monty Williams To Orlando

SIXERS: 76ers Trade Monty Williams To Orlando Will somebody explain to me how you can do this? Or even how it makes sense. You can trade a player that's been on your injured list for the entire season. A player that has been rumored to be contemplating retirement ... to another team for draft pick. And by the way, you gotta give up a draft pick of your own and cash! Is this some kinda salary cap magic?
