BOCA RATON, Fla. — Hey, go easy on Sidney Crosby. At least that's the message from Pittsburgh Penguins general manager Ray Shero.

Crosby recently passed on an invitation to appear on the "The Late Show with David Letterman" and has been taking some criticism for the snub.

Shero came to the defense of his team's captain. He says it should be noted how much traveling and playing Crosby has done since the Olympics and the many interviews he's had.
