I think a lot of people are overreacting here. What people fail to understand is that roughly 50% of the spots will come from world rankings.
Are world rankings any assurance of an athlete's current state of fitness?
What if a woman was injured all of 2018 and fell off the rankings and then podium'd at Atlanta in February, but "only" ran a 2:30 because of the Atlanta hills?
Do they get to go to Tokyo? I think not by the way this is written?
