Gordon can become an RFA next year. Not in their wildest dreams do the Magic think they can get a top rookie with 2 or 3 more years left under contract.
The price might not be obscene; maybe a decent pick (Mem?) and a young player as filler. Or maybe if you send Marcus Morris (the salaries work) you send a much worse pick (Bos 18).
If we sent Morris, that might also help in finding minutes for Gordon. This year you might be able to close out with Horford, Gordon, Tatum, Brown, and Irving. (And, well, that sounds pretty interesting, right? Small-ball athleticism with great length and switchability, five shooters...).
Next year I'm not so sure, and that's where I wonder. I've got the finishing five for next year penciled in as Horford, Tatum, Hayward, Brown, Irving. I don't see Gordon breaking in there. Will he want to come off the bench, and does that even make sense? Won't he get an offer above $7.2 (his option for next year) from somebody else if he tests the market - in which case I think he's gone and you gave up a year of Morris.
