While I get what you're saying...Roy got his contract based on his 2011 play and the assumption he'd be as good or better.
He's been incredibly worse. Does he even have 1 game of better than 50% shooting?
He's shooting in the mid 30's, missing layups and tip's, turning it over...his defense has been sensational, but he's a massive negative force offensively. How incredible does he have to be defensively to offset his absurdly bad offense (so far)?
Right now, they're both playing like $5M-$8M guys. I assume Hibbert will be better...but at this exact moment give me Javale. At least he wont take 12 shots a game and miss 9.
