The Penguins had just dropped a 1-0 heartbreaker to the Capitals for their sixth straight loss, and defenseman Paul Martin, seated at his stall in the locker room, was white as a ghost.

Martin had been ill for days and admitted Saturday that he probably shouldn't have been playing. But Martin, the Penguins' highest paid defenseman who underperformed earlier this season, felt a sense of obligation.

It turns out, he cares a lot more than his stoic demeanor and low-key game suggests.

"People don't understand that about him," assistant coach Todd Reirden said. "Paul's "care factor" is there all the time."
