DENVER -- The first completed pass of quarterback Patrick Mahomes' NFL career turned out to be a sign of things to come.
On a third-and-10 during the Kansas City Chiefs' opening possession of Mahomes' first career start, he took a shotgun snap and fired into a small window between two Denver Broncos defenders, deep down the middle, to tight end Demetrius Harris for 51 yards.
In one throw on a 17-degree December day in Denver, the legend of Patrick Mahomes began.
"That pass told you everything you needed to know about him," Chiefs guard Laurent Duvernay-Tardif said.
