Reversion to the Mean
On April 7, 2003, the Syracuse Orangemen defeated the favored Kansas Jayhawks 81-78 to claim the Division I Men’s College Basketball championship. Certainly, future NBA Hall of Famer Carmelo Anthony, did his part putting up 20 points and collecting 10 rebounds, but it was the freshman Gerry McNamara that made the difference for SU that day. He hit 6 of 8 three pointers in the first half putting Syracuse up 53-42 at the break. Kansas played catch-up the rest of the game and couldn’t quite get there. Of course, making only 12 of 30 free throws is a surefire way to lose most ball games, let alone a championship against a talented team.
How unlikely was G-Mac’s first half performance? Well, it stands as the record for threes made in a half of a championship game. G-Mac was able to hit 6 or more threes in a game a total of 9 times in 135 games. I do not believe he ever hit 6 in a single half before or after the game against Kansas. So that’s once in 270 halves. In fact, the odds of making exactly 6 of 8 threes for a player whose ultimate success rate turned out to be 400 of 1,131 (35.4%) is 2.3%. That means if you turned G-Mac loose into 135 games and he took exactly 8 threes in every half, you’d expect him to hit 6 in a half a total of 6 times.
That first half was unlikely.
