He isn't a FA until the end of 2016 so we will still have him on contract for another whole year
What year do you think it is now?

His contract runs through '17, but next year is a player option. I can't imagine he's going to play for $10m next year when the price tag for a 27 year old All-Star caliber wing who averages 20ppg will be much, much more. Jerebko, Zeller, and Young or a rook plus later of Boston/Dallas first?
Don't want to give up much for a half year rental. But Toronto is not going to trade him unless their season takes a serious turn for the worse (like season ending injuries to Lowry and Carroll plus losing records in Dec and Jan) and they decide to go for a quick tank.
