Every team does that after an interception or fumble now and days. You're telling me that a group of 53 men lost their focus because maybe a 1/5 of them went to the endzone to celebrate after a turnover? And this then permeated from the coaches to the players, and effected the offense stalling? Stop. I don't mind bootlicking, but this armchair psychology take is ludicrous. I've seen the 49ers and other teams win games after that, so why didn't they lose focus either in those games? Because it wasn't the Super Bowl? Why doesn't celebrating in the endzone after a score have the same effect and trainwrecking an entire team's confidence for the rest of the game? The entire league would be low scoring if what you are insinuating had any semblance of truth to it.
