This warning comes directly from Mark Glowinski, the veteran offensive lineman who has started every game for the Giants this season at right guard.

Take care of business this Sunday because if not, bad things can happen.

“Sometimes things slip between your fingers and you want them back,” Glowinski said Wednesday after practice.

The Giants have in their grasp a berth in the NFC tournament, needing one win in their last two games to produce the first playoff appearance for the franchise in six years. The first crack at this comes Sunday against the Colts at MetLife Stadium.

“You don’t want to relive a moment over and over again on the bad side,” Glowinski said. “You want to make sure you’re doing whatever you can to execute the plays that are in front of you to eliminate what-ifs.”

Glowinski knows all too well what can happen when a team does not take advantage of the task at hand. Seeing the Colts across the field this weekend will stir a memory Glowinski would rather not be awakened.

He was in his fifth and final year with the Colts down the stretch of the 2021 season and the prospects of getting into the postseason looked bright. The Colts had rebounded from a 1-4 start to win eight of 10 games and entered Week 17 needing one victory in their final two games to get into the playoffs. They lost at home to the Raiders on a last-second field goal.

Still, the Colts appeared safe. All they had to do was beat the 2-14 Jaguars to keep playing. The Colts did not come close, losing 26-11 in Jacksonville to finish 9-8 and stay home for the playoffs.

“You could tell early on what was going on,” Glowinski said. “Even the week before we needed to win that game as well so it’s not like it was down to that last game. It definitely comes down to in that moment, that’s your playoff game. Whatever we can do to make sure we’re maximizing every moment, every play to put ourselves in this situation.

“I think it’s more of us not taking anybody lightly, making sure you’re in the moment, making sure you’re executing your plays, making sure it goes back down to fundamentals and technique, making sure you want it more.”

Glowinski this past offseason signed a three-year, $18.3 million contract as new general manager Joe Schoen’s first step in rebuilding the offensive line. Glowinski’s performance has been solid and not spectacular but he has been a dependable piece, playing every snap in 13 of his 15 games.

It sounds as if Glowinski is eager to recount the misery he experienced one year ago to his new team as the Giants get set to face his former team.

“All I can do is refresh everybody, use all the time I’ve had in the past for situations of wins and losses to remind guys it’s here,” Glowinski said, “and right now and we need to execute and make sure we give everything we can.”
