In her post-race interview
Lisa Uhl admitted that when her shoe came untied, Shalane told her to stop and tie it and she'd go to the front and slow it down for her. They went from running mid 70's to 80+. The slower pace also caused some contact which left Notosha Rogers on the ground and sprinting to catch back up.
She only finished 14 seconds off the "A" standard and that's falling down and going out in a 16:16 for the first 5k. A more even first 5k and no fall and she's got 31:45. Those who didn't need the "A" worked together to make sure no one else got it and now Rogers isn't an Olympian. You shouldn't get an advantage in an OT race because your teammate happens to be one of the best runners in the World.
It's dumb too because in the end she didn't even save Uhl the spot, but gave it to Janet Cherobon-Bawcom back in 7th place.
