There are guys in the NBA who come off the bench when teams need a defensive presence. Guys like Taj Gibson, Nick Collison, Luc Mbah a Moute and
Tracy McGrady Vince Carter Shane Battier, who thrive on shutting down their opponents. Jason Richardson, a starter, is not one of these guys. Not legally anyway.

This is, in case you were unaware, against the rules. But only if the referee actually notices it. If not, then it just makes Jason Richardson the single-greatest bench defensive specialist in the league.
