Barry Trotz was livid on the Islanders' bench.

The Lightning's Ondrej Palat had just scored to give his team a 2-1 lead in Game 2 of their playoff semifinal series on Tuesday night. He did so as the referees and linesmen missed that the Lightning had seven skaters on the ice at the same time, which should have stopped play.

Trotz yelled at the referees, failing to get their attention. Later, his assistant coach, Lane Lambert, used his video tablet to call up a screen grab, showing the Lightning with too many men on the ice. Trotz pointed to the visual aid as he continued to bellow at the officials following the second-period goal.

"The second goal hurt quite a bit. [Because] if they get the third one, there's a little bit more separation," Trotz said after the game.
