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. But there’s something far more telling about that play. The throw. Or, rather, the decision to throw it at all.

Quarterback Patrick Mahomes spent some time before Saturday's preseason game running up and down the Kansas City Chiefs sideline, yelling, jumping and psyching himself up for his first game action since last season's Super Bowl.

The Chiefs recovered a Greg Dortch fumble on the opening kickoff, and with a penalty tacked on, began their first drive at the Arizona 13. Isiah Pacheco went 8 yards on first down before Mahomes threw incomplete to Tyquan Thorton. Cardinals rookie cornerback Will Johnson, though, was cited for defensive pass interference.
