While his younger brother Travis has been living the high life, Jason Kelce has been enjoying the simple pleasures months after retiring from the NFL after 13 seasons.

As Jason, 36, gears up for his new role as an ESPN analyst on Monday Night Football this upcoming season, he has spent much of his time with family and building projects at his home in Philadelphia.

A source close to the Kelces revealed to the US Sun that Jason has spent much of his team working on his man cave and home library.

‘He loves the simple life,’ the source said. ‘Jason is the perfect anti-star.’

The source later shared that the former Philadelphia Eagles center spent $15,000 on his man cave.

Being a sports memorabilia fanatic, Kelce dedicated some of his fortune into items such as iconic gloves and jerseys.

Outside of sports, Kelce studied history and literature at the University of Cincinnati. After hanging his cleats up, he reportedly spends around $2,000 a month on vintage book copies for his personal library.

When not reading or hanging out in his cave, Kelce reportedly loves mowing the grass on his $4,000 lawn mower.

Furthermore, the source said Kelce spends ‘over $1,000’ on meat when hosting parties and pairs them with an impressive selection of craft beers.

‘Jason is definitely keen to learn more about the beer business,’ the source revealed.

The revelation comes not long after Jason and Tavis became investors in Garage Beer together.

While the 2018 Super Bowl winner is unsurprisingly making up for lost time with wife Kylie and daughters Wyatt, Elliotte and Bennett, the source emphasized the difference between him and Travis when it comes where they spend their money.

‘He doesn’t care about fashion,’ said the insider, who claims Jason is content in his favorite pair of sneakers – a pair of Nike Air Monarch’s worth $70 – Birkenstocks or flipflops.

‘A basic pair of Levi’s and a shirt will do for him. He lives a simple life and enjoys the simple pleasures.’
