The NFL preseason provides opportunities of all shapes and sizes, with game plans and intended playing time always etched lightly in pencil on a coach's prep sheet. Anything can happen to dictate whether those plans are followed during a game.

Brownlee made a heck of a touchdown catch, the highlight of the Chiefs’ 20-17 loss to the Cardinals in the preseason opener here in Arizona — and, ahem, most certainly the highlight of the 48 seconds Patrick Mahomes spent on the field.
