Taylor Swift effect is REAL, says retired Giants QB Eli Manning, who believes pop star's romance with Travis Kelce is good for the NFL: 'I have three daughters and when the Chiefs are playing, they are watching that game'

Two-time Super Bowl champion Eli Manning says he's witnessed Taylor Swift's impact on the NFL first hand.

The retired New York Giants quarterback appeared on Good Morning America to preview Monday night's Super Bowl rematch between the Kelce brothers: Kansas City Chiefs tight end Travis and Philadelphia Eagles center Jason.

Inevitably the conversation turned to Travis' love interest, Taylor Swift, who has become a near fixture at Chiefs games, much to the delight of Manning's three daughters.

'I think it makes it fun,' Manning told GMA's Robin Roberts. 'I have three daughters, 12, 10, and 8. When the Chiefs are playing, they are watching that game and looking for Taylor. It makes them enjoy the games and get into it.'

Manning's three daughters – Ava, Lucy, Caroline – appear to be more interested in soccer than football. Since their father bought into the NWSL-champion Gotham FC, the trio have been seen regularly at the club's games in Harrison, New Jersey. He and his wife, Abby McGrew, have four children in total, including son, Charlie.

Of course, Manning was speaking about the Kelce brother rivalry because of his experience playing his older brother, Peyton, on three occasions.

'I really don't like talking about it too much since I was 0-3 in those games,' the 42-year-old Eli joked. 'It is a sensitive subject for me.'

Eli's Giants fell to Peyton's Colts in 2006 and 2010 before the elder brother moved on to Denver and beat his younger sibling again in 2013.

'It was so unique, and I remember the times just before the national anthem, you are sitting there on the 40 or 50 50-yard line, you look across and you see a big brother on an NFL football field about to play a game,' Eli continued.

'That is the real fun part.'

Of course, like the Kelce brothers, the Mannings were never on the field simultaneously during any of their games against each other because they both play on offense.

'When you are both on offense, you are not going against each other, you're going against the other team,' Manning said before imagining his slow-footed brother playing defensive back.

'If Peyton was playing defense, if he was playing cornerback, I know where I'd be throwing every single time. That's not the case.'

As for Travis Kelce's performance, Manning hasn't noticed any issues since he began his high-profile relationship with Swift earlier this fall.

'I think he is handling it very well,' Manning said. 'You're dating maybe the most popular person in the world right now, so there's a lot of questions about it. I think he is handling everything very well. He is staying focused on playing football, doing his job. It has not affected his play. If anything, it has arisen his level of play these last few weeks. When she is at the game, he seems to score a touchdown every single time.'

Swift is not expected to be at Monday's game as she continues her tour in South America, where one fan recently died due to suspected heat exhaustion.

Meanwhile her parents – both Eagles fans – are expected to be in attendance at Arrowhead Stadium in Kansas City, where they are expected to meet Travis' folks on Monday.
