Lighten up Francis! Seriously, I think if you did it proportionally, you'd be looking at more like 75 seconds.
Ignoring that, I think there's more competition on the guys' side of things. Also, there's no one on the guys' side that's quite as good in comparison to the rest of the field as Goucher and Flanagan are to the women. Yoder-Begley's huge effort notwithstanding.
Sure, some of the women fell asleep at the switch a bit, but if you had the guys' race won in 27:15. And the next five times were 27:20, 27:33, 27:35, and 27:45, and then there was a gap back to sixth that was about one minute, would you be surprised by that? Given the level of competition out there, that would seem reasonable to me, but the odds of the winner being that fast is low. A race like that wouldn't be unbelievably dissimilar to the women's race.
If we had two guys who were capable of running 26:45 and they ran 27:15, how would the others react to them in the race? Food for thought...
