Quarterback Josh Rosen was presented his Under Armour All-America Game jersey Thursday afternoon during a presentation at Bellflower (California) St. John Bosco in front of his friends, family, teammates and coaches.

"It's awesome," Rosen said. "Every single event is special in its own right. All of this is notoriety for the school, the staff, and helping Bosco as an institution. I'm just enjoying the benefits of some hard work."

It's not the first time all eyes have been on Rosen, and it likely won't be the last. While plenty can change between now and 2015 spring ball practices, there is a very good chance that UCLA will be looking for a new starting quarterback, as Brett Hundley could opt to enter the NFL draft. As an early enrollee, Rosen, the nation's No. 19 overall prospect and No. 1 pocket passer, would likely find himself in that battle, and there isn't much doubt as to Rosen's ability to handle that kind of pressure.

"Right away his maturity is going to separate him," St. John Bosco head coach Jason Negro said. "Josh's maturity is off the charts. His knowledge of the game and his preparation is off the charts, and I definitely believe that the similarity between what UCLA does offensively and what we've done offensively here at Bosco over the last four years is really going to allow him to step in and compete right away."

Negro cited Rosen's growing understanding of defense, as opposing coaches throw more and more complex schemes at Rosen, is an aspect of him game that will help him immensely in college as well.

Rosen isn't one to shy away from a challenge and understands exactly what kind of opportunity could be waiting for him at UCLA. Rosen cited a nationally televised game against Las Vegas Bishop Gorman and an appearance in last year's state title game as situations in which he's been asked to take snaps in pressure situations in front of sizeable audiences.

"I think playing at a program like this, against the talent in the Trinity League and Pac-5, has prepared me to where I can, not seamlessly transition over, which is not even possible, but maybe have a less bumpy transition and maybe move into college with a cleaner entry than most," Rosen said. "Especially because I'm getting there early, so I can take the mistakes on the chin in the spring and once all my buddies get up there in the summer, I can help them along and be a leader for them."

For now though, Rosen has his sights set squarely on finishing his senior season on a strong note. He's told the UCLA coaches that they don't need to use their weekly recruiting call on him if the time can be better spent recruiting other prospects and said that from Sunday through Friday, his focus is fully on his Bosco team.

"The Gorman loss was as frustrating as can be and it made us hit the reset button and refocus as a team more internally rather than externally," Rosen said. "I think we're headed in a positive direction. We're definitely on the path to repeating a state championship."

Five questions with Josh Rosen

If you could start a team with one recruit from the 2015 class, who would it be?

"I think I’d say Alize [Jones]. I could put him at left tackle. I could put him at receiver. I could put him at linebacker. If I could multiply him by 21 and I could be the quarterback, it’d work out relatively well."

What is your first football memory?

"My favorite early football memory is being trapped out of our practice. We practice at South High and the gates were shut and we had no way of getting into practice so we drove through the high school hallways and ended up clipping off one of his mirrors trying to get to practice on time."

If you could take on any pro at their sport, who would it be?

"I would like to play Andy Roddick in tennis."

Why do you wear your number (3)?

"I have a weird OCD thing about everything I do is in multiples of three. Ever since kindergarten or first grade, the number three has always appealed to me. In youth basketball and soccer I was never too picky about it and just got what came to me. I was never the kid in the front of the line pushing and shoving for numbers. But I got a choice and picked three and thought it looked good. They didn’t really let me steal it from Bryce Treggs my freshman year, but I got it my sophomore year and I like it."

What is something people might not know about you?

"I DJ for fun. I play the guitar. I’m interested in astrophysics -- if I had a little more time I’d love to major in it, but I don’t know if that will end up working out. I spend most of my time watching documentaries and YouTube videos on the origins of the universe and Stephen Hawking’s string theory."
