More poor asset management by the Raptors.
Why let go a 24 year old PG/SG who had a pretty good year for you last season at such a low price? Why not keep him as the primary backup since it seems like he still has some room to develop and Lowry might only be here for 2 years? Oh right, because no one else in the league wants Jose Calderon right now no matter how hard the Raptors try to trade him and the Landry Fields offer sheet.
At this point though, I'm not surprised. I also fully expect James Johnson to get traded for peanuts even though he is probably better than every other SF currently on the roster or signed to an offer sheet.
