Alberto Salazar might pull her out of the 1500 and put her in the 8000 instead because "he is reassessing the advisability of putting Cain in a race along side" Abeba Aregawi and Jenny Simpson.
God forbid we run a race with fast people in it when we're not in peak shape! We could lose!!!
Maybe he's worried she'd get in over head trying to race them and get sniped by Elise Cranny in the last 100?
Either way, pretty lame. I don't blame Cain, this is typical Salazar stuff and she's not going to go against her coach (at least not at this age). There's only so many blows to his ego he can take and Rupp just got smoked by Collis Birmingham so he's got to be careful for a while.
