Apparently, someone actually DOES have a perfect bracket through 48 games. That's notable, because in all the years that the NCAA has been reviewing millions of brackets, the best start they've ever seen is perfection through 39 games.
And even if this bracket busts soon, there's a good chance it could beat the OVERALL record, which is correctly guessing 54 of the 63 games. They really only need to get two of the four divisions right to hit that mark.
For what it's worth, whoever is responsible for this bracket seems to be playing things fairly safe. They're not predicting any upsets in the next round.
Although that itself would be an outlier, because the NCAA notes that the top eight teams in the tournament - ALL the 1 and 2 seeds - have NEVER all advanced to the Elite Eight in the 34-year history of the tournament.
And while there hasn't been as much MADNESS this year as there has in the past, there HAVE been some significant upsets: An 11-seed beating a 6-seed, THREE 12-seeds upsetting 5-seeds, and a 13-seed taking out a 4-seed.
There's no definitive math on the odds of this happening. But if you're curious, the THEORETICAL odds of having a perfect bracket at this point in the tournament are more than 1-in-281 TRILLION. Or specifically 1-in-281,474,976,710,656.
