From a Prof at UCLA and RAMS fan:
I'm telling you those rumors about him not being nice aren't true.
It's something that has followed him his entire career, people assume he's an icehole but he's not.
Even people at UCLA figured him to be an icehole, and coaches, especially ones like ******* Jim Mora would fan those flames.
At UCLA I would teach a few classes, most of them dealing with advanced physics and astronomy, and one basic one, known as a "blue bag class" AKA a class that a bunch of student athletes would take because it wasn't super hard or demanding (we didn't get into any real physics in it, very basic astronomy).
I would teach football players, basketball, baseball, track and field, pretty much all of them. Josh Rosen was the only student athlete I've ever seen who wanted to know why things happened. The rest were only good at regurgitating the answer if they knew it. Most would use their "tutors" to cheat for them, they'd get test questions before hand from other TA's or just outright steal them from an office, it was a huge pain. Rosen was different, he didn't just want to know that the Sun would eventually die, he wanted to know the why and the how, he wanted to understand it, really understand it, from all angles.
He would sit with me after class and ask questions, explain it in his own words to see if he really understood things, was always incredibly friendly.
Some people bitched because they wanted to to home or do something else, but those aren't teachers or instructors in my eyes. Those are just dictators who want to make sure they stay the smartest guy in the room.
The NFL is filled with Jeff Fishers, and not a lot of Sean McVays. If Rosen was a coach, he'd be more like McVay in terms of his thought process.
He just doesn't have the good looks or charisma to make everyone love him immediately.
But if you actually sit and talk with him, you'll see he's one of the nicest guys you'll meet. The nicest student athlete I've ever taught.
Again, I don't have issues with hating on him for being a Cardinal now, but let's keep it at that.
