Do you play poker, Texas Hold em? If you do, you'll know that having the better hand before the final card, or in this case the final 2 cards come.
What would you rather be facing the turn, and the river with, a pair of Aces vs. a pair of Kings or a pair of Kings versus a pair of Aces? When it comes to this final section, we're holding the Aces, compared to Carolina holding the kings. Buffalo has 3 of a kind.
There's always a chance someone gets lucky (ex. Carolina here), but if you look at it, the team with the best odds and the team with the 4th best odds (although our odds were almost the same as Ottawa and Phoenix's) made the final 3. So odds do matter.
