The Carolina Panthers and Denver Broncos are set to square off in Super Bowl 50, but where does each team stand in the Super Bowl hierarchy since Pro Football Focus has been grading every player on every play in the NFL season?

Below is a ranking of the past 18 Super Bowl participants, according to the PFF grading system.

1. 2012 San Francisco 49ers

PFF grade: plus-527.4

The 2012 49ers had a truly dominant roster from top to bottom, but couldn't come up big on the biggest stage. Their offensive line was one of the best PFF has ever seen, with every starting member earning high grades, paving the way for Frank Gore and Colin Kaepernick to run from their option attack. Both the defense and special teams were formidable. This is a team that definitely underachieved.

2. 2013 Denver Broncos

PFF grade: plus-435.3

The Broncos got waxed in the Super Bowl by the Seahawks, but it was more about meeting a horrible matchup than it was about meeting a better team. Peyton Manning sat at the helm of a record-setting offense and the defense was good enough to hold its own. This team just found its kryptonite in the big game.
