As we approach the 2018 NFL Draft, UCLA Bruins quarterback Josh Rosen remains one of the most highly-coveted prospects available at the position. He's expected to go early in the first round, but some scouts and general managers still have their doubts.

Questions about his brash personality and quality as a teammate continue to persist despite multiple UCLA players and coaches vouching for him. Still, in the grand scheme of things, neither of those are the biggest concern.

Rosen struggled to stay on the field his sophomore year before going down with a concussion in 2017 that kept him out of UCLA's bowl game. In three years with the Bruins, the signal caller managed to start 30 games for the UCLA. He only won 17.

While his lack of success in the win column can mostly be attributed to the roster around him (which was often lacking in terms of offensive line depth and defensive prowess), Rosen takes the blame for the losses and admits that he wishes he could've been more successful in college.

Courtesy of Sporting News' Alex Marvez, who transcribed a portion of Rosen's interview with himself and Gil Brandt on SiriusXM NFL Radio:

“I wanted to win more,” said Rosen, who was 6-5 in the games he did start last year. “To be honest, I really didn't accomplish a lot of the goals that I set out to do, which was really frustrating. All of the individual stuff kind of comes along with team success.”

Overall though, Rosen believes he learned a lot in his time at the collegiate level that can help him as he adjusts to the NFL:

“But I also learned a lot in my three years at UCLA. I learned how to handle a lot of ups and a lot of downs — adversity, success — so it was a blessing in disguise. UCLA is an incredible school. I wouldn't have attended anywhere else, even in retrospect. I'm glad I went through those three years for good and bad.”

Rosen is considered to be the most polished QB entering the draft after running a pro-style offense in college, but some scouts don't think he has the same potential as USC's Sam Darnold, or even Wyoming's Josh Allen. We'll see how it all shakes out during the draft, which starts on Thursday, April 26th.
