It’s always tough for young QB’s to go on the road and beat the Patriots. This Sunday was no different. 

It was the first loss of the season for the Chiefs (5-1) and first loss as a starter for Kansas City’s 23-year-old QB Mahomes, and he did it all in front of his girlfriend Brittany Matthews

Mahomes ended his night passing for 352 yards and four touchdowns, setting a Chiefs’ record for five straight 300-yard passing games.
