When it comes to his stats, you can check that box off too. Last season at UCLA, Rosen started 11 games and threw for 3,756, 26 touchdowns, a 62.6 completion percentage, and a 147.0 quarterback rating. Those may not seem like the most impressive stats, but if you saw the talent around him, you would be impressed with those stats as well.
Rosen was a starter as a true freshman at UCLA where he played in 13 games, threw for 3,669 yards, 23 touchdowns, and a 60.0 completion percentage. Before his season ended early during his sophomore year, he threw for 1,915 yards, 10 touchdowns and a 59.3 completion percentage.
Throughout his career, Rosen has been productive. He has lacked big time weapons while at UCLA, and his offensive line has been questionable at times. His production would have been better if he was able to stay healthy, instead of missing time because of injuries. However, he still showed why he was elite due to his mechanics and smarts.
The biggest knock against Rosen on the field are the interceptions. While he is extremely accurate he threw 11 interceptions his first season at UCLA, which is understandable because he was a freshman. But as a junior where you expect growth from a player, he threw 10.
He will have to work on decision-making at the next level, but with his accuracy paired with a better line and receivers on the outside, I believe he will take much better care of the ball.
