In the aftermath of the Jets' 30-10 loss to the Buffalo Bills, HC Aaron Glenn stressed the importance of internal evaluation amid the inevitable ebb and flow of an 18-week NFL season.

"I'm disappointed in how we played yesterday," Glenn told reporters Monday morning. "I thought Buffalo beat us in our brand of football. … This is a brick-by-brick mentality for us. We're going to continue to work and we're going to continue to build and do everything we can to make sure we stay aligned on what we're trying to do as far as this football team."

Glenn, who said he will look at himself and his staff first to determine ways to improve, did not have a definitive update on QB Justin Fields, who sustained a head injury in the fourth quarter of Sunday's game. Glenn said Fields is in concussion protocol and will continue to be evaluated throughout the week, but he expressed confidence that QB Tyrod Taylor will be ready to step in if called upon.

No matter who the signal caller is, as the Jets take the field for practice this week to prepare for a Week 3 road game against Tampa Bay, the focus will be on looking ahead in what Glenn described as "a week-to-week league."

"Here's what I do know -- I know this is an instant coffee league," Glenn said. "From the media, to the fans -- everyone expects this -- when you just start, OK, we're going to the Super Bowl. But, we've all played Legos before. And you have to make sure everything is aligned, and you keep stacking it day by day. And to me, that's how I look at it. I understand the outside noise, and I'm not affected by the outside noise. Because I know exactly what we're trying to build here. And I wish it was instant coffee, but it's not. These things take time. My confidence or the coaches' confidence or the players' confidence is not going to be shaken. We're going to continue to do the things we've got to do to build this."

Glenn has firsthand experience building a program from the bottom up. When he arrived in Detroit in January 2021, the Lions were fresh off a 5-11 season in which they finished at the bottom of the NFC North.

And from there, things took time. In his first year as a defensive coordinator, Detroit finished 3-13. During his second season, the Lions posted a 9-8 record and nearly earned a playoff berth. The team then exploded for 12-5 and 15-2 finishes during the 2023-24 and 2024-25 seasons, respectively.

It's no surprise that Glenn understands the importance of patience following good and bad performance alike. He spoke Sunday about the need for honest evaluation and getting back to work quickly. And as the Jets look to turn their attention to the next opponent, striving for consistent performances will be top priority.

"To me, it's getting the guys to play at a level that we need to play on a week-to-week basis," Glenn said. "And I will tell you this -- I'm always going to look at myself first no matter what. Good game, bad game -- no matter what. I want to make sure we play a brand of football that we talk about every week. And when we don't hit that brand, I always look at myself. … You're going to hear that from me every week. It always starts with me, and then it filters down to everyone else."
