Everything started perfectly for the Senators, who were up 2-0 against the Lightning, while the Islanders, also vying for a playoff spot, were down 2-0 against the Panthers.

However, the situation changed dramatically when the Senators allowed four unanswered goals, losing 4-2, and the Islanders rallied to win 5-2. This loss puts the team's playoff aspirations at risk.

The adverse result adds to the pressure, as every remaining game is crucial to secure a place in the postseason.

Coach Travis Green surprised by choosing James Reimer as the starting goalie, even though Linus Ullmark, with a salary of $8.25 million per season, should have started the game.

Reimer, who had been signed in January, had a .884 save percentage before the game.

Green's decision raised doubts about roster management and the use of Ullmark, especially considering the upcoming games and the need for rest.

The Senators' inability to capitalize on scoring opportunities was a key factor in the loss.

Key players like Tim Stützle and Brady Tkachuk failed to convert on penalty shots and clear opportunities during the game.

This lack of effectiveness in front of the goal has been a persistent problem, affecting the team's chances at critical moments.

The difference between the Senators and teams that secure their victories, such as the Canadiens and the Hurricanes, who did take advantage of scoring opportunities, was highlighted.

The comparison underscores the need for the Senators to improve their ability to score in key situations.

Efficiency in converting opportunities is crucial to compete in the playoffs.

The absence of Jake Sanderson was felt in the defense, especially in his ability to win defensive battles and get the puck out of the zone.

The team also played with a disadvantage in the composition of the defense, with five right-handed defensemen and only one lefty.

The Senators are preparing for an important game against the Panthers on Tuesday, looking to recover from this loss.
