re: Why is the SB so often a blowout?

Super bowls for the most part have lived up to the hype and been better games than most of the regular season games the past 10 years at least. The steelers cardinals game was great, saints was close til the pick 6, seahawks patriots came down to the wire, broncos panthers was a defensive struggle but the broncos never could pull away. We were due for a blowout
