Archie Manning Is Making His Debut on Peyton and Eli's ManningCast — Which He Watches 'Religiously' (Exclusive)

After three seasons, Archie Manning is finally ready to make his debut on the ManningCast!

Archie, 75, exclusively tells PEOPLE that he will join his sons Peyton and Eli Manning on their popular weekly broadcast for the New Orleans Saints' matchup against the Kansas City Chiefs on Monday, Oct. 7.

The brothers often invite big-name guests to join them on the show — Miles Teller and Bill Belichick are two who have joined this season — but Monday's broadcast will mark their father's first appearance on ManningCast, which he tells PEOPLE he and his wife Olivia tune in for weekly.

"We watch it just religiously. We don't miss it," Archie shares, adding that he'll make his debut during the fourth quarter of the game.

But the former Saints quarterback says it wasn't his sons who convinced him to appear on the show. Instead, "It was somebody from Omaha Productions," says Archie, joking, "Maybe [Peyton and Eli] didn't want me and Omaha overrode them."

Archie says he's most looking forward to a "good game" between Kansas City and New Orleans (where he played from 1971 to 1982) when he joins Peyton and Eli on their show.

"Kansas City's riding high," Archie notes of the 4-0 Chiefs. "The Saints have lost two tough close games, they need a win. They really need a win."

And while the former quarterback is "obviously" a Saints fan, Archie tells PEOPLE he's also a "big fan" of Kansas City head coach Andy Reid and quarterback Patrick Mahomes.

"So I really hope we have a good game," adds Archie, whose grandson Arch Manning is making waves in college football.

Arch, 19, whose father is Archie's oldest son Cooper Manning, is the quarterback at the University of Texas. On Sept. 14, Arch had a 67-yard touchdown in which he reached nearly 21 mph in Texas's win over UTSA Football.

Archie tells PEOPLE that it's been a joy to watch the next generation of his family's success on the field. "Sometimes, I think Olivia and I kind of pinch ourselves," he says.

"I know we did during a few years there when both boys were in the NFL, you know, back-to-back Super Bowls, back-to-back Super Bowl wins, MVP's, we kind of pinched ourselves. And then we've again, the last couple weeks with Arch getting some playing time and having some success. So we feel very blessed."

Archie will be on the ManningCast on Monday, Oct. 7, which starts at 8 p.m. ET on ESPN2.
