pure flukey dumb luck 
Au contraire! In the history of all sports (I saw this on ESPN a few yrs back), the single greatest example of homefield advantage occurs in Rd 2 of the NFL playoffs (since the institution of the wild-card weekend). Given a playoff bye week, Rd 2 home teams have won greater than 75% of their games. No other home field advantage anywhere in any sport has construed greater than 62% advantage (might be even lower, if memory serves).
So picking a nice round number like 75%, you have less than a 1% chance of correctly picking 3 road wins and one road loss*.
Not at all surprising, especially considering the Panthers were this yr's only team to go 8-0 at home.
*in any 4-game parlay where the road team is at 25%, the odds = 0.25 x 0.25 x 0.25 x 0.75. Correctly picking the one team in these four with the 75% chance of winning introduces a further 25% odds. Hence the final result is a 0.00879 chance of getting it exactly right.
So stand tall Tinka-Cat!
