NY Giants’ new offensive line coach aims to ‘build their toolbox’

No. 10 overall pick Francis ‘Sisi’ Mauigoa will be the starting right guard for the New York Giants. A 23-year-old rookie starting at that spot is a big change for a Giants’ team that had Greg Van Roten, whose pro career began in 2012, at right guard for the past two seasons.

That, though, is not the only big change for the Giants on the offensive line.

Mike Bloomgren is the team’s new offensive line coach, replacing the popular Carmen Bricillo, who did well in that role over the past two seasons. The Giants’ offensive line was 15th in the NFL last season using the Pro Football and Sports Network Impact Score as a measuring stick, its best standing since beign 16th in 2019.

“I have a lot of respect for Carm,” Bloomgren said recently. “I think he did a great job with the room. So it’s great that they have such a good baseline of knowledge and an understanding of this great game.”

This will mark only Bloomgren’s second season as an NFL offensive line coach after he held that job with the Cleveland Browns a year ago. Bloomgren, though, is an accomplished, veteran coach.

How has Bloomgren approached trying to help a mostly veteran offensive line group?

“I think we’re always trying to build their toolbox,” Bloomgren said. “We spent the first part of our time here in February and March in addition to preparing for the draft and free agency, we were really trying to evaluate these guys and what they did exceptionally well and what we thought maybe a tool here or a tool there could help them with.

“When you put in any new system, which we did, and we’re slightly different in some ways and very different in others. But the techniques change. The names change. And so a lot of it has been really trying to build the foundational knowledge so this room can go out and play football fast.”

No Giants’ offensive lineman feels Bricillo’s absence more than Eluemunor. This marks the first time since 2018 that Eluemunor is not on a team where Bricillo is an assistant.

“It’s definitely been different,” Eluemunor said. “I think Bloom and Carm are two great O-line coaches. Obviously, Carm helped me to get where I am right now. Bloom’s thing is you’ve been here and you’ve gotten here but how can you take that next step. It’s been really cool just picking Bloom’s brain, being out here just seeing little things I can get better at.

“Bloom and (assistant offensive line coach) Grant (Newsome) are helping me with the little technique things that will make a big difference come Sundays.”

Bloomgren is hoping to give Eluemunor “a couple tools”, and not reinvent the wheel.

“When we’re talking about schematics, when we’re talking about techniques, this guy protected the passer really well last year,” Bloomgren said. “Really proud of what Jermaine did. Really glad we have him back in the building.

“And so, again, there’s not a whole lot there. There’s a couple tools you could add, a couple things, hey, think about this. But for the most part, like in pass protection, you’re really going to say, like, block your man.

“And we’re going to give him tools to do so.”

It wasn’t a secret that the Giants were a better pass-blocking that run-blocking team in 2025. The Giants, of cours, are now a John Harbaugh coached football team. One thing that follows is a renewed emphasis on running the football, and inevitable changes in how Giants’ offensive linemen will be asked to execute those blocks.

“I look at the potential there and the ability, and really you look at what they did in the past to get a baseline and to understand what you can try to improve,” Bloomgren said. “This system is going to be so much different than what they’ve done in the past from a run game standpoint.

“I couldn’t be happier with how the group has attacked this offseason … even though we’re not in pads and it’s football-like, not football, you’re still seeing great growth out of these guys.”

Bloomgren had a glowing early assessment of the prized rookie.

“Completely in love with football. And I think not just playing football, but the ability to prepare the right way and the desire to prepare the right way,” Bloomgren said. “I think he comes in with a great baseline of knowledge. I think you look back at him being coached by Alex Mirabal (at Miami) and nobody in college football is teaching it better and getting a better product out there than Alex. And so that’s really nice.

“You’re able to see the college film, see how it will translate to our system, and it just made Sisi a real good easy proposition if we could get him.”
