Philadelphia Eagles center Jason Kelce screamed at the top of his lungs, citing all the slights his Eagles team had endured while underscoring their role as the ultimate underdogs. The powerful moment took place Feb. 8, 2018, at the iconic Philadelphia Museum of Art as the Eagles celebrated their first NFL championship since 1960.

"It was epic, man," said Jason's brother, Travis Kelce. "It was the greatest speech ever in Super Bowl history."

Adding to the scene, Jason was dressed in a leprechaun outfit provided by the Avalon String Band, which has participated in a Mummers Parade, a march in jester-like costumes, since World War II.

"I still don't what the hell that was, man," said the Kansas City Chiefs tight end who is also known for his ostentatious wardrobe. "If there's anyone to pull that off, it would be him."

Though not at the championship parade, Travis attended the Super Bowl in Minneapolis.

"It was awesome, man," Travis said. "I kind of forgot how my family reacts to how we make plays out on the field."

Travis is used to being a playmaker. A three-time Pro Bowler, he has topped 1,000 receiving yards the past two years.

But with the trade of quarterback Alex Smith to the Washington Redskins, Travis has a new role as the senior member of a talented group of offensive weapons that includes running back Kareem Hunt, wide receivers Tyreek Hill and Sammy Watkins and first-year starting quarterback Patrick Mahomes.

"It's not a seasonal vet back there," he said. "He's learning on the go."

Everyone knows about the prodigious arm strength of the second-year Mahomes, whose father had an 11-year career as a Major League Baseball pitcher.

But so far he has impressed teammates with leadership and moxie. During halftime of an Aug. 25 preseason game against the Chicago Bears, he told Travis that the team needed his energy in the second half after the tight end had an uncharacteristically sloppy first half, which included a false start penalty.  

"Everyone believes in him," Travis said. "He's capable of taking this thing by the horns and taking us far into the playoffs."

If Mahomes fulfills that potential, it could allow Travis to accomplish his goal, the same one his brother memorably attained last season.

"Win the Super Bowl to match him," he said. "That would be nice."
