To be honest, the Pac-12 blog's 2013 All-Pac-12 team wasn't difficult to pick. That's probably why it has few differences when compared to the coaches' All-Pac-12 first team.
The most difficult position to narrow down was the secondary. The Pac-12 blog also went with Oregon State defensive end Scott Crichton over Stanford's Ben Gardner, who was first team with the coaches, despite missing the final four games of the season.
The only team that didn't place a player here is California. Stanford led the way with four position players and five overall.
