IT is NOT leaving. Sorry but can someone name me another legitimate scorer on this team right now? Maybe Horford, possibly Bradley, but both average less than 19 PPG. IT can average 21+ a game, and even when he struggles he has a knack for getting to the line and scoring from there.
Unless they can miraculously nab a Westbrook or Lilliard kind of guard.. IT will get extended. I think it comes down to Smart/Bradley, choose one, let one leave.
OR don't sign a max free agent next two seasons and keep all 3 (unlikely though)
