Year of the Quarterback profile: St. John Bosco’s Josh Rosen (VIDEO)

St. John Bosco head coach Jason Negro said Josh Rosen "has everything you need" at the quarterback position.

Negro said that when Rosen was a sophomore.

Through the years, Rosen has proven his head coach right as he’s in the conversation for best quarterback in the country. The UCLA commit helped lead the Braves to the PAC-5 semifinals as a sophomore. As a junior, he helped the team to a perfect season and a national championship.

Rosen returned for his senior season with a new cast of characters but it hasn’t hindered his production or that of his team as he’s in position to win a third consecutive Trinity League title.

Catch Rosen and St. John Bosco as they take on Servite tonight at 8:30 p.m. on FOX Sports West.

Strengths: If you talk to Negro or St. John Bosco offensive coordinator Chad Johnson, they rave about Rosen’s command of the offense. It’s something he’s had since he was a sophomore. As Negro mentioned, Rosen has everything you need to be successful at the position. He has a cannon for an arm but is still able to put touch on the ball when needed. His accuracy is supreme and he’s a very underrated runner.

Weaknesses: Rosen doesn’t lack confidence. He’s certainly confident in himself and his abilities. However, that confidence has rubbed some the wrong way. One would think you’d want your quarterback to be sure of himself.

Key stat: 13. The number of wins Rosen has as a starting quarterback in Trinity League play in as many games.

Quotable: "Josh Rosen’s probably the most polished," famed quarterback coach George Whitfield of Rosen at the Elite 11.

Final thoughts: If you look at Rosen’s body of work, it’s pretty amazing. For starters, he’s 4-0 against Mater Dei — there aren’t many who can say that. The Trinity League, largely considered to be the best league in the country — aplace where its teams beat one another up. Rosen doesn’t know what it’s like to lose in it. He’s suffered just two losses in his career on the field. The St. John Bosco quarterback has thrown for over 7,000 yards in his career with 79 touchdowns and just 17 interceptions. That’s a little greater than a 4:1 touchdown-to-interception ratio.
