Does quality of opposing QB's played during the regular season determine Super Bowl winner?

There is always much debate over whether the quality of the opposing QB and/or teams played during the regular season have a direct effect on the eventual Super Bowl winner?

In other words does the Patriots playing the overused expression "tomato cans" hurt their Super Bowl chances.

My short answer is no. Here are the last 5 Super Bowl winners and the QB's they beat to get to the Super Bowl.

The 2013 Seahawks, 2012 Ravens, 2011 Giants played horrible QB's in the regular season.

You decide.
