Say Buffalo's number was 1523, Ottawa's is 1524, Arizona's is 1525, and Vancouver's is 1526
So the last ball would be the number 3, and we have already selected 152 (hence why each of the 4 teams above are still alive)
For some reason, there are more 4's left than 3's, 5's, or 6's. So Ottawa has the highest chance of winning
But a 3 was selected, so Buffalo won
