The Arizona Cardinals opened the preseason with a 20-17 win over the Kansas City Chiefs Saturday night at State Farm Stadium. They fell behind 14-3, but backup quarterback Jacoby Brissett threw two touchdown passes in the second quarter, and then both teams only scored a field goal the rest of the way.

The preseason debut for Patrick Mahomes spanned all of 48 seconds and included all of one pass and 1 yard. But hey, one touchdown, too. Mahomes' day was short in a Chiefs 20-17 loss to the Cardinals in Glendale, Arizona - so we can halt any big-picture conclusions about the outcome.
