Another way of saying "Most road playoff wins" to me is saying "My team is never good enough in the regular season to get a bye because I am so inconsistent at my position so we always have to play on the road." Do road playoff wins really matter? Pretty sure home ones count just the same. How many rings does he have? Zero. This is the first super bowl appearance. They dont beat Denver without Denver's secondary falling asleep 3x.
Also if you want go off just percentages. Aaron Rodgers road playoff percetage is the same as Flacco's and offensively his teams score over a TD more per game. Eli Manning, Ben Roethlisberger, and Fucking Mark Sanchez all have better road winning percentages. So lets not overreact to a mediocre stat.
