As Allyson, Abby can run the 100m to 400m, 200m being her best event, although she's not as good as Allyson was.
She might get an Olympic gold medal in an individual event (very unlikely in Paris, bigger chance in LA), but she will shine in relay events.
I can see her winning lots of silverware in relays, just like Allyson did, even more now there's the mixed 4x400 (and we might have the 4x100 soon).
