The last few games on the schedule essentially have been exhibitions for the Tampa Bay Lightning, who may not want to carry a season-worst five-game losing streak into next week’s playoffs.Having lost four straight games in regulation, the Lightning (45-30-6, 96 points) will try to regain momentum Thursday when they close the regular season at home against the Detroit Red Wings (35-36-10, 80 points).Lately, losing has been the way for the defending Eastern Conference champions, whom many pundits say will simply “flip a switch” when the postseason commences and regain the form that sent them to the Stanley Cup Final the past three years.After Tuesday’s 4-3 home loss to the Toronto Maple Leafs, coach Jon Cooper’s bunch left the ice in defeat for the eighth time in the past 11 contests (3-8-0).That skid sports two four-game losing streaks sandwiching a trio of wins over the Carolina Hurricanes, Washington Capitals and New York Islanders.Cooper didn’t put much importance in the setback against the Maple Leafs — his club’s first-round opponent in the playoffs. He likely feels the same about the season finale against the Wings.Toronto scratched star forwards Auston Matthews and Mitchell Marner, defenseman Mark Giordano and No. 1 goaltender Ilya Samsonov.”There was zero intensity in that game, there was none,” Cooper said. “… That was an exhibition game. We’ll get something out of it at some point when we go back and look at the tape, but they had players that play lots of minutes for them out of the lineup.”The match featured 20 penalties and a pair of fights, including former teammates Luke Schenn, now with the Leafs, and Pat Maroon. In all, there were 14 power plays between the teams.Added Cooper after his side’s 0-for-8 showing on the man advantage, “It was a weird game. I don’t know if anybody got anything out of that game. Clearly there was a mandate to call some penalties.”The Red Wings have won two of the three matchups against the Lightning but was shut out by goalie Andrei Vasilevskiy on Feb. 25 in Detroit. He made 45 saves in a 3-0 win.
