Even cocksure Mario Chalmers sometimes needs words of encouragement, it seems.

After yet another subpar game Wednesday, Chalmers received a call from his former college coach, Kansas' Bill Self.

"Always good to hear from Coach Self," Chalmers wrote on Twitter. "The one person who always has faith in me outside my family."

Chalmers has fallen in and out of favor so many times during his five years with the Heat that this latest trough is no less surprising than his brilliant run of play to begin 2012. Remember the first half of last season? While Shane Battier struggled to find his form from the outside, Chalmers was the Heat's most consistent outside threat. He led the Heat in three-point shooting and earned a place in the All-Star Game's three-point contest.

But the only consistent thing about Chalmers' NBA career, other than his unflappable confidence, has been his inconsistency. He's shooting 32.7 percent from three-point range (16 of 49) through the first 20 games of the season. Of the Heat's three-point shooters, Chalmers ranks sixth in made threes behind Ray Allen (37), Battier (33), LeBron James (27), Rashard Lewis (17) and Mike Miller (17).

Chalmers is the Heat's entrenched starter at point guard, but as his numbers have waned so too has his role at the end of games. In the Heat's past three games, Chalmers has watched fourth quarters from the bench. He last saw action in a fourth quarter in the Heat's blowout loss to the Knicks. Chalmers played less than three minutes in that fourth quarter and had two points.
