Bradley isn't leaving town for that crap. Jimmer somewhat helps our 3point shooting problem but not enough to pursue.
Career numbers
Bradley 6.9p/1.7r/1.4a/0.8s/0.4b/1.4t/2.6f/20.4m shooting .438/.335/.755 with one 2nd team all defense
Patterson 8.3p/4.4r/0.9a/0.4s/0.4b/0.8t/1.8f/22.1m shooting .495/.372/.728
Bradley is an undersized shooting guard. Patterson has great height as a 3/4. Both are essentially the same age with the same years in the league, but Patterson hasn't been hurt and has played 42 extra games.
I get that Bradley is a pretty darn good defender, but Patterson isn't a slouch defensively and he isn't a waste offensively, on the boards, or virtually everywhere else like Bradley is. Boston absolutely should cash Bradley in because he isn't going to be much better than he is right now and his value certainly won't be higher.
