Bianca isn't altogether wrong, if a little extreme. Forgetting those at the world best level for the moment, that two HSers are faster than anyone in the NCAA, is concerning. Two 19yo (College age women) were 1 and 2 at the OG. So don't tell me women can't run the 800m fast at that age (College). Even discounting the number of foreign women in the NCAA, the development is not as much (in depth) as it should or could be. Seriously, other than the free education at a good school (Stanford) what do Willis and Whittaker have to gain athletically? Do they stagnate running against slower women for 4 years (other than presumably Gorrarian moving into the mix the year after)?
As to the Brits, both Hodgkinson and Reekie could be in the ncaa this year, running against who? So I think Bianca's point might be that the depth in NCAA is weak and should be better.
With the men, many of the underclass NCAA 800m champions have turned pro before their senior year. Will this pattern (like Mu) now become common for the women?
