Matt Rizzo has currently run 2:59 and 1:50 this weekend, and I'd be shocked if he doesn't follow up today in the 800. If he runs 1:51 or faster, that is easily a comparable triple.
Shocked you must be, then, since Matt Rizzo did not run an individual race. His brother, Alex, finished 8th in the 800 in 1:53.91.
I can't disagree with you about Verzbicas. Don't know any others you vaguely referred to, however, so unless one or more are named, only Verzbicas's weekend extravaganza is in that lofty stratosphere of all-time off-the-charts greatness. Affolder's weekend was spectacular, but just not GOAT.
