I ran @ NCC (a few seasons with Dan Mayer) and am therefore biased. However, I find it incredible that Dan Mayer wasn't included on the original "top D3 of last 15 years" list! His 3K/5K/10K times & records, many national titles and great Wisconsin accent earn him a place on ALL top D3 lists!
Oh, and the 28:48 was run in early April at the Chicagoland Championships @ NCC (not Nationals - also @ NCC that year). I was out of school by then, but was fortunate enough to see the race. He outdueled Charles Mulinga (of local D2 "power" Lewis University) and more importantly, the wind. Most people there guessed the wind was strong enough to have cost him at least a second per lap. At that point of the season, only Bob Kempainen's 28:47 was faster on the US list.
And the sub 14:00 5K was actually a 13:52 victory at the INDOOR (!) Nationals! He sprinted to the lead (about a straightaway up at a lap and a 1/2) en route to lapping the field (most twice).
