Eli Manning is no longer the starting quarterback for the New York Giants. That’s not sitting well with some Big Blue alumni.

The last time Eli Manning wasn’t the starting quarterback for the New York Giants, Facebook didn’t exist. Aaron Rodgers was still in college. Usher’s “Yeah!,” featuring Lil’Jon and Ludacris, was the number one song in the country.

And the New York Giants had only two Super Bowl championships to their name.

Tuesday, the news broke that Manning, a two-time Super Bowl MVP, was no longer the team’s starting quarterback. As you’d imagine, that’s not sitting well with Giants alumni, some who played with him and some who didn’t.

Defensive end Osi Umenyiora, who spent all but two seasons of his 11-year career with the Giants, says that Manning deserves much better than this.

Carl Banks, one of the most underrated linebackers in NFL history and a member of the Giants’ first two Super Bowl-winning teams, wasn’t able to hold his emotions in check like Umenyiora.

Phil Simms, the greatest quarterback in Giants history before Eli showed up, gushed over Manning rather than take shots at the organization.

Brandon Jacobs, who along with Tiki Barber formed one of the franchise’s most lethal backfields—remember Thunder and Lightning?—stood up for his quarterback.

For David Diehl, who spent all but one season of his 11-year career keeping Eli upright—something the current offensive line has struggled to do, seemingly since Diehl retired—questioned the organization’s decision-making ability.

Diehl’s linemate—and Eli’s center for seven years—Shaun O’Hara went the emoji route to express his emotions.

Kurt Warner, who mentored Manning before he took over as starting quarterback in 2004, went off on the organization, via NFL.com’s Tom Pelissero:

After Amani Toomer and Odell Beckham Jr., Plaxico Burress is arguably the best wide receiver Manning has thrown to over his Hall of Fame career. The man who shot himself offered a more subdued reaction to the news.

But perhaps the most accurate reaction to the madness comes from David Carr, who spent the last four years of his career serving as Eli’s primary backup.
