This is a similar scenario to Alan Webb going pro after a year at Michigan. Sounds like he got the same deal he was being offered immediately out of hs. No one was questioning that decision and I don't see why people would here. Who do you think is more likely to make an Olympic final:
19 year old male 336 1500m runner
19 year old female 200 800m runner
19 year old female 49.8 400m runner
49.8 is the best mark
