RAPM last season
Brandon Jennings: 0.6 on offense. -3.2 on defense
Jeremy Lin : 0.6 on offense. -0.2 on defense.
Granted, he was not nearly as awful in the past few years, still bad but not nearly as bad (more like -0.8 -0.9 on defense.)
The upside is that he's A. still 23 despite being around forever B. doesn't throw the ball away much C. can kinda shoot the 3.
I figure Detroit is now a pretty firm first round exit team. that's not terrible certainly. and that they managed to do this without trading away Drummond should be commented at least. at worst, Jenning is at least functional, albeit very flawed. which is more than you can say for poster boy Brandon Knight.
