Darren Waller Says Travis Kelce Will Become G.O.A.T. Tight End, 'He's That Good'

Move over Tony Gonzalez, Gronk and Shannon Sharpe -- Travis Kelce will go down as the greatest tight end EVER ... so says Raiders star Darren Waller, who tells TMZ Sports the Kansas City Chiefs TE is on his way to G.O.A.T. status.

Of course, the debate has become a hot topic recently ... with 33-year-old Kelce skyrocketing to the top of some lists with his incredible play over the course of his 10-year career.

Waller is definitely Team Kelce -- 'cause he says when it's all said and done, #87 will be the best to ever do it.

"He's that good," Waller told us this week. "I feel like he'll finish as the greatest tight end of all time. I don't think that's farfetched. It's awesome to see what he does."

We also asked Waller about Patrick Mahomes, who lost Tyreek Hill in the offseason to the Dolphins ... and he praised the SB champ for Kansas City's offense remaining at the top of the league.

"It's incredible," the 30-year-old said. "I heard a lot of people saying his job was going to get a lot harder this year with no Tyreek Hill and he wouldn't have the same level of success."

Of course, Mahomes and Hill created magic over the course of the five years they played together in Kansas City, routinely torching opposing defenses in the regular season.

Some thought Mahomes and the Chiefs offense would regress without Hill, but that wasn't the case for #15, who put up MVP-caliber numbers all season en route to the Super Bowl.

Speaking of the SB ... Waller says the game is a toss-up, but he predicts the Eagles will get a lot of pressure on Mahomes when they need it most and believes Philadelphia will win.

Waller got into some non-football talk ... telling us he has some new music on the way.
