As a 49er fan since the Montana days of the 1980s, tonight’s game was very disappointing. They outplayed the Chiefs for 3 1/2 quarters and then their defense completely let them down.

San Francisco coughed up a 10-point fourth-quarter lead. Its offense couldn’t stay on the field to prolong drives, the defense couldn’t come up with timely stops, and a final-minute drive came up short as the Kansas City Chiefs emerged with a 31-20 victory at Hard Rock Stadium.

Thanks to last year’s 13 – 3 win by the Patriots over the Rams and this 11-point win by the Chiefs over the 49ers the average point differential between teams in the Super Bowl for its entire history has now dropped below two touchdowns to 13.91 points for the first time in 54 years.
