UCLA quarterback Josh Rosen is one of the most gifted quarterbacks coming out of college in recent years but his numbers don't show it. Rosen dealt with a below average roster behind him. While that shouldn't be an excuse for a player who could have dominated the PAC-12, his offensive line was bad and Rosen was under pressure a lot more than others and took an uncomfortable amount of hits. Despite the lack of help from other areas of the team, Rosen led the Bruins to a bowl game in his freshman and junior seasons, where he was able to start the majority of his games other than minor injuries that kept him sidelined for a couple of games.
In his first season as a true freshman at UCLA, Rosen started all 13 games for the Bruins. In that time he completed 60 percent of his passes, throwing for 3,669 yards, 23 touchdowns, and 11 interceptions. In the bowl game against Nebraska, Rosen managed to complete 65 percent of his passes for 319 yards, 3 touchdowns, and 2 interceptions in a losing effort.
After the Bruins’ game against Arizona State in 2016, Rosen missed the majority of the season with a shoulder injury.
Going into his third season and what was expected to be his final season at UCLA, Rosen’s expectations were high and he was looked at as one of the top quarterback prospects for the 2018 NFL Draft. Rosen completed 62.6 percent of his passes for 3,756 yards, 26 touchdowns and 10 interceptions. The Bruins were in the Cactus Bowl against Kansas State, where Rosen didn't play. There were concerns of him intentionally sitting out of the game but the UCLA staff assured that Rosen’s absence was completely due to concussion-like symptoms.
Rosen is the most pro-ready and polished passer in this year’s draft class. He is seen as a safe pick but his ceiling may not be as high as Sam Darnold or Josh Allen because those two are more raw as prospects. If the Buffalo Bills manage to move up in the draft to select the quarterback of their choice, there is a good chance that Rosen is at the top of the list.
