Definitely a trend going on. Denver won all those playoff games and the SB w no QB (no disrespect to Peyton but he was so shot). Seattle beat Denver in 2013 w D and running against the Gase high flying 55 TD pass offense. Look at the Vikings - D and running. D / run game has always won the SB (only exception was Rams - Titans) but now I think we will see more playoff teams that get there via ground and pound than years past. By the way, last year's SB featured two great defenses and teams that could run the ball.
