That first-half clash was caught on camera and flooded social media. The incident was revisited time and again during the post-match debrief, too.

Who could have blamed Reid had he wound the clock back, to the 2013 NFL draft, when he picked up the phone and called the younger Kelce brother the Eagles in 2011 and was now considering bringing Travis to Kansas City – reprimanded the tight end over his behavior and apparent volatility.

As Kelce later recalled, Reid all-but said: ‘Are you going to screw this up? I need a mature guy. I don’t need a guy who’s going to come in and be silly.’More than a decade later, Kelce accepted that he had crossed a line in Las Vegas. But Reid shrugged off the meltdown. A ‘cheap shot,’ he jokingly called it. ‘I didn’t see him coming, or I would have forearm ripped him.’

It was a masterclass in how to defuse a bubbling PR disaster. But also another glimpse into the special relationship that has helped propel two brothers and one family towards superstardom.
