I think you missed the part about how she doesn't give a rat's arse about the social aspect of being on a team. She is socially awkward and running with girls that are closer to her in ability is not going to make her enjoy the social aspect of running any more. Also, as a female runner, I have to say that I do not consider my college years running with other college women to be the best years of my life. There is a lot of petty nonsense that goes on with women's teams, and they are distracting. You are surrounded with eating disorders and social politics.As a post-collegiate, I love my training partners. Eating disorders don't last post-collegiately and for the most part everyone is choosing to be there. I think she will find a lot more satisfaction training with Salazar's group, or continuing to train remotely, than she would on a college team.
Wejo - the social component when she's on a team with a group of girls running mostly a minute slower than she would over 1500m probably means she would be a little lonely at training.
Running for a top collegiate team with a load of girls who run maybe 10 seconds slower than her (and are stronger at the longer stuff) and could even be ahead of her in training (re: Salazar's comments that she doesn't train like a 4:05 runner) might be a real draw and much more social.
