"This is a five-alarm fire," coach Jon Cooper said.
The Presidents' Trophy-winning Lightning trail the Columbus Blue Jackets 2-0 in the Eastern Conference First Round after losing 5-1 at Amalie Arena on Friday.

Worse yet, since scoring three goals in the first period of Game 1 on Wednesday, the Lightning have looked nothing like the team that tied the NHL record for wins in a season (62), that led the League in goals (319) and that finished first on the power play (28.2 percent) and penalty kill (85.0 percent).
They've been outscored 9-1 in the past five periods, including 4-0 on special teams, with three goals coming against their penalty kill and one against their power play.
Game 3 is at Columbus on Sunday (7 p.m. ET; NBCSN, SN360, TVAS, FS-O, SUN).
"We had a wonderful regular season statistic-wise, our wins, both our special teams finished first, but the regular season is different than [the Stanley Cup] Playoffs," Cooper said. "Things just happen so fast. All of a sudden it's 0-0 and you're all excited going into Game 1 and all of a sudden you're down 0-2 at home and alarms are going off.
"Have we faced a ton of adversity this year? We haven't. I've been in the League six years. and it probably hasn't gone any easier than it has this year. So now we've got some adversity."
The Lightning responded poorly to the adversity they faced Friday.
They were down 2-0 after the first period and 3-0 after the second. They had a glimmer of hope when defenseman Mikhail Sergachev scored at 5:00 of the third, but they couldn't convert on a power play that started 51 seconds later, and Columbus forward Riley Nash made it 4-1 at 9:06.
