A key note from the article is its list of the left tackles who've started in the last five Super Bowls: Bryant McKinnie, Joe Staley, David Diehl, Matt Light, Chad Clifton, Trai Essex, Jermon Bushrod, Charlie Johnson, Max Starks, Mike Gandy. The writer, Andy Benoit, notes that all of these players- with the exception of Staley- were mediocre players at their position that year. He argues that "skill players who can get the ball in space" are far more valuable in the modern league.
