Because, comparatively, that's how slow the Olympic final was.
The winning time of 3:50 is about 23 seconds slower than the PB of the fastest man in the field (Kiprop, 3:26.69)
Compare that to the average top time in the NCAA, we'll say 3:37, and it makes you realize how slow the Olympic final was. Not complaining, just wondering if we have ever seen a race that slow and tactical on the collegiate level.
