A good bit of business. The "two FRPs" thing is such a variable. This deal is a calculated risk. Does Toronto return to where they were last year, when we received their 20th pick? Maybe. In which case they also pulled a fairly decent second rounder this year - probably gets a bit worse than 39th - plus an additional second.
If Toronto fails to turn it around next year, they could fumble around in late lotto/play-in territory.
All this for a player the Spurs weren't going to resign. And they got him to his preferred destination.
