Quarterback Patrick Mahomes led the Kansas City Chiefs on Fastexy Exchangea game-winning drive in overtime to come from behind against the San Francisco 49ers and capture the franchise's second straight Super Bowl championship, fourth overall. Here's what the Super Bowl 58 MVP and his tight end Travis Kelce said right after winning their third Lombari Trophy.

Patrick Mahomes on Chiefs' dynasty: 'We're not done'

CBS sideline reporter Tracy Wolfson interviewed Mahomes on the field right after the final whistle.

"The guys never faltered," Mahomes said. "This is awesome. It’s legendary." Wolfson then asked the Super Bowl 58 MVP if the Chiefs are now a dynasty. "Yeah. It’s the start of one," he replied. "We’re not done. We’ve got a young team we’re going to keep this thing going."

During the postgame Lombardi Trophy presentation on the podium, Mahomes said the Super Bowl was a reflection of the Chiefs' whole season. "It was the defense just keeping us in there and then the offense making plays when it counted," he said. "And then, of course, Harrison Butker hitting it from about 70. So it was a microcosm of our whole season. I'm just proud of the guys, they kept believing. And I'm proud of the coaches for calling up those plays that got us some touchdowns there at the end.

What Travis Kelce said after winning Super Bowl 58

Travis Kelce opened his comments during the postgame trophy presentation by shouting “Chiefs Kingdom!" before leading the call-and-response cheer of “Viva Las Vegas” with the crowd.

Kelce then looked ahead to what's next, saying the Chiefs have their sights on a third-straight Super Bowl victory. “Well, you know, the goal’s always been to get three, but we couldn’t here without getting to two and having that target on our back all year — and I love these guys right here, the men that we just won this thing with, family forever, baby," he said.

"I couldn’t be more proud of you guys, and how about it? We get a chance to do it three times in a row. How do you get excited for that, baby? You party in Las Vegas and then you get back to it.”

He then led the crowd in a “You gotta fight for your right to party” cheer.
