"You don't need to lecture me. . . ."? Pot meet kettle. You are trying to make this more about you and your friend, but the reality is in all of the media pieces on Myles, it is clear that for Myles, academics and life outside of basketball receives much more focus than for other players. And I am well aware of how graduate scholarships work with top engineering and STEM students, so no need to lecture me on that.
First, Myles is much closer to home and his family, which probably mattered a lot to him, as he seems very close to his mother and father. Rutgers was his sole P5 (and probably his best) offer out of high school, and this was his chance to play close to home at the end of his career versus across the country.
Second, without discounting the quality of Rutgers Computer and Electrical Engineering, he is earning a degree from UCLA, which is a much more prominent and higher ranked higher than Rutgers.
Third, Myles is smart enough to know that he was going to a much better basketball team (consistently and currently ranked top 10) and that he was going to have to earn his minutes and role on the team.
As far as "significantly less minutes" that is in the eye of the beholder. He is playing 18.2 minutes per game, and is starting fewer games than he did at Rutgers, but see third above. Last year, he played 24.7 minutes per game, but with the emergence of Cliff and the need to give Cliff more minutes, he may have been playing fewer minutes at Rutgers as well. Nobody knows how that would have played out. In the video I posted, he seems perfectly happy with his place at UCLA, including basketball.
