Riley Believes Heat Lack Mental Toughness

Heat president Pat Riley believes that he has a talented team, but says they lack a certain toughness.

"What I think the team lacks, a little bit, is mental toughness. A real mental toughness," Riley said.

"Most of the teams in the NBA find those moments that are a blip on the radar screen, where everything looks like it's going down the drain, and it's [about] developing this mental toughness every night."

Miami is 2-3 on their current six-game homestand.
