Former Longhorn (always a Longhorn) stud Brendan Hansen broke the world records (both of which he previously held) in the 100m and 200m breaststroke at the National Championships. Though I  don't have the stats to back it up, I'm sure that Ian Crocker, Brendan Hansen and Aaron Piersol, all Eddie Reese students, have broken more world records in the past three years than has any other trio (as long as that trio excludes Michael Phelps).
