The Kansas City Chiefs have made a beautiful start to the NFL season, defying all expectations on their way to an 8-1 record.That's good enough for the best mark in the AFC and is joint-first in the entire National Football League with Sean McVay and the now beaten Los Angeles Rams, who dropped their first game of the season last night against the New Orleans Saints.At the heart of the Chiefs amazing run has been quarterback Patrick Mahomes, who has taken to the NFL like a duck to water after spending his rookie season on the bench learning from Alex Smith before being unleashed on the league.Mahomes has been incredible so far, dropping video game numbers week in, week out as well as breaking NFL records left, right and centre through his first nine starts. And he carried that form on yesterday as the Chiefs went up against the Cleveland Browns, who came into the game fresh off firing Hue Jackson and Todd Haley.And Mahomes balled out again as the Chiefs rolled to 8-1 with a 375-yard passing performance that also saw him throw for three touchdowns in a 37-21 win in Cleveland.But there was one moment from the game that sticks out above all others. Something we genuinely haven't seen before. It turns out that there is a way to stop Mahomes. And it wasn't something the Browns defense did. No, it appears that only the referees can stop Patrick Mahomes. The Chiefs scored on their first three drives, and on the fourth, with just a few seconds remaining, they tried to get into field goal range at the end of the half.KC got to the line while the clock was stopped, in order to spike it as soon as it began, so they could save their timeout for the field goal unit.And then it happened. Mahomes got called for intentional grounding for spiking the ball while the clock was stopped, and it resulted in a 10-yard penalty and then a 10-second runoff that could've ended the half had the Chiefs not used a timeout. Check it out here...

We've never seen the refs make that call before. But it worked to stop Mahomes, who threw his only INT of the game on the next play as he had to pull out something spectacular to get them back in scoring range but couldn't make it happen with timers at zero.
