OH man, I know you are kidding but don't get me started with those kinds of people who think that way.
Every year when a playoff game features a matchup of divisional rivals in which one team went 2-0 during the regular season, indoubtedly there will be at least one analyst who confidently says......
" (insert 0-2 here) will win this game because it's tough to beat a team three times in one season."
Is it tough to beat one team three times in one season? Yes, it is (all things equal, a 12.5% chance of this happening), but that's not really the situation being presented here.
Instead, the probability question becomes, what are the odds one team wins all three GIVEN THAT THEY HAVE ALREADY WON THE FIRST TWO?
All things being equal, the probability of winning all three is 50%. But the reality is that the teams probably aren't equal, and the 2-0 team is 2-0 because they are better. So the odds would actually be greater than 50% for them to win the third game.
Let me use a more drastic example to make my point.
If the Pats beat the Bills 26 straight times, what are odds that they win the 27th game? PRETTY FRIGGIN GOOD.
But you'll have that one misinformed, dope analyst say "no, I'm taking the Bills because it's tough to beat a team 27 straight times"
