Every so often Super Bowl MVP goes to someone with underwhelming stats who made a few extremely impactful plays. That's the route I was imagining. Maybe he makes a couple spectacular 3rd and long pass breakups and stands Pacheco up on the goal line, in addition to a big interception or fumble recovery.
If no one else lights it up and those stand out as the decisive plays, it could happen.
I'm also trying to think what a KC loss would have to look like.
