Mario Chalmers had just completed yet another strong performance this postseason. As he was about to hop on the cart that taxis players from the locker room to interview podium following Wednesday's victory, he couldn't help but crack a joke to the driver. "You need to put some spinners (rims) on this," Chalmers said. "Hook it up." This is Chalmers, the brash, overconfident jokester who has evolved from liability to legitimate third-scoring threat for the Miami Heat. With Chris Bosh sidelined the past seven games, it has been Chalmers filling the scoring void with 3-point shooting and drives to the basket.
