Natosha Rogers - 10,000K. She finished 2nd at the 2012 Olympic Trials but lacked a time qualifier. She has it this year and has come out of nowhere (after 3 down years) to be a contender in the 10k. If she is anywhere near 1-3 positions on the last lap, I would not count her out, she has a great kick.
Alysia Montano - 800m. Her moment has been stolen too many times. She deserves a re-do Olympic experience and all the press that comes with it. She is effervescent.
Emily Infeld - 10,000K. Always overlooked in HS and in the NCAA. Her turn for the spotlight.
Ajee Wilson - 800m. I want her potential to finally meet opportunity at a Global Championship. At her best, I believe she can challenge Semenya and Nyonsaba. I'm hoping she leaves Rio with a medal.
Ariana Washington - 100/200. LB POLY HS PRIDE. hero at the NCAAs. she has much room for improvement, especially with her form (it has improved leaps and bounds since high school already). Anyone who has been closely following her career know that she is the future.
Ashley Spencer 400/400 hurdles. She must regret passing on the Olympics as a junior. Im not convinced she is a hurdler. I still think she has the most potential in the 400m among the current crop (even more than Okolo). Watching her win the NCAAs and World Juniors was a thing of beauty. Her last 100 in those races hints at greatness.
Kori Carter - 400 hurdles. It's been awhile, but I haven't given up on her potential. Her ability to fight the last half of the race has always inspired. Her close come-from-behind victories in CA HS meets and the NCAA were no accident, they were the marks of a champion in the making who fights to the line. If she can stay healthy, she will be unstoppable.
Candace Hill in the 100/200 - could be the next Usain Bolt. She can break 22 this year.
Tori Bowie - 100/200 she will be this year's star. Hard not to root for.
Raevyn Rogers - 800. We haven't even begun to see what she is capable of.
Sydney McLaughlin - 400h/400. Could be the next Allyson Felix in terms of talent,prodigy-status, and endorsements.
