Given Brown's shooting struggles I can understand leaving him out of the honorable mentions. But Barnes over Tatum? That's silly to me.
That said, Pelton has always been an analytics guy and the analytics this year LOVE Barnes, like an absurd amount. He's 13th in the entire league in EPM.
Personally I don't see it, the guy has look meh when I've seen him. But he's the sort of all around players some metrics love.
