Saying that sadly skips over MANY great performances by US athletes over the years. These are better:
Bernard Lagat: wins 1500 WC, wins 5000 WC, wins loaded Zurich 3k field (2007)
Bernard Lagat: 7:32.49 / 12:54 AR / 3:34 (2010)
Alan Webb 3:30.54 / 3:46.91 AR / 1:43.84 (2007)
Bob Kennedy: 6th in Olympics 5000 / 7:33.96 / 12:58.21 AR / 7:31.96 (9th fastest in world) --- and that is FOUR in a row (1994)
Deena Kastor: 2nd in World Cross Champs / 14:54 AR (roads) / world leading 2M time 9:35 / 30:50 AR (track) --- four in a row
Suzy Hamilton: all this in a *one* week period: 3:59.40 (2nd Berlin) / 3:59.43 (1st Rieti) / 4:01.08 (2nd GP Final)
I am sure people who want to do the research could find good triples for people from the 80s or Khannouchi and some of the women. Solinksy has been great, but he is definitely not alone in the triple, and the 2nd fastest American on American soil isn't exactly big bragging rights in my book considering how infrequently fast 5000s in the US are run in peak season.
