The talk started the week before the All-Star break, when Orlando Magic coach Stan Van Gundy said the Heat's Mario Chalmers had positioned himself among the upper half of the league's starting point guards. Then came Jeremy Lin's appearance at AmericanAirlines Arena with the Knicks and the debate about where he stood among the NBA's playmakers. It was a debate heightened when he was outplayed by Chalmers. Yet for as much improvement as has been made by Chalmers, and for as endearing a story as Lin's has become, the reality is the league is loaded with quality point guards.
