Stamkos pulled no punches with his comments about the way his team played in a 4-1 loss to the New York Rangers, its third straight defeat, fourth in the past five games and ninth in regulation over the past 13 games.
The Lightning were outshot 20-3 in the first period, 35-11 after two and 42-25 overall.
"It's embarrassing, the first 20 minutes," Stamkos told NHL.com seconds after tossing the final scoresheet out of his hands. "I mean, 20-3 in shots, we need to wake up. There's really nothing else. Our goalie kept us in the game, thank God, but it's embarrassing."
