What do I expect from OJ Mayo?

That's what I was thinking, sitting in the ashes of another "must-win" game that slipped, specifically, from OJ Mayo's fingers. I've never really watched anyone like OJ, he's one of those guys for whom the eye test doesn't work. He's the Mavs' best three-point shooter, and their best finisher (not in terms of completion percentage, but in terms of the athleticism of some of his drives and finishes), and he does it against the other team's best wing-defender.

But he's not a guy advanced stats love. His 16.86 PER this season is 84th, tied with Greivis Vazquez, just behind Mike Conley. While Vazquez and Mayo both, in some ways, merit consideration for the Most Improved Player award, Mayo was never supposed to be Greivis Vazquez. He's at 3.8 winshares on the season, tied with Kyle Lowry, Jason Kidd, Ersan Ilyasova, Brandon Jennings and Goran Dragic for 64th, just behind Darren Collison. His career similarity scores so far are unfortunate, Luther Head, Mario Chalmers, Malik Sealey....
