WATCH: Alex Smith completes comeback with overtime TD run

Whether it’s the San Diego Chargers’ inability to close out games or Alex Smith’s magic, something crazy happened in Kansas City on Sunday.

Down 24-3 more than midway through the third quarter, Smith and the Chiefs staged a monumental comeback against their division rivals to open the season.

By virtue of two touchdown passes from Smith and a touchdown run from backup turned starter Spencer Ware, Kansas City ultimately forced overtime.

Then, in the extra stanza, Smith proved that there was still some magic left in the tank.

The good old walk-off quarterback keeper to win a divisional game in overtime.

Overall, Smith completed 34-of-48 passes for 363 yards with three total scores and an interception.
