The UCLA Football team ran out of gas at the end of 2016 season. The Bruins forced a system on offense that did not work as well as had a rash of injuries, including QB Josh Rosen, which had them finish 5th in the Pac-12 South with a record of 4-8, 2-7.
This was after the Pac-12 media writers voted for the Bruins to win the South Division at the start of the season. UCLA was also ranked 16th in the 2016 preseason AP poll. Unfortunately we know what happened to those rankings as the Bruins fell into oblivion.
