I was a junior in hs in 01, I guess the way birthdays fall I'm a couple years younger than the three of them (35 now), but right there close. I remember there being real excitement about all three. Webb probably the biggest at that time with his mile times, kinda captured the attention of the casual fan.
For careers Webb has his AR mile, some us 1500m wins, and an Olympic team. Coming out of high school if you said he wouldn't be competitive on the world level I think most would agree that would be a disappointment.
Hall has the 59:43AR and only sub 2:05 by an American (even though it doesn't count). He ran that half at 24/25 years old and he had me convinced he would be challenging at the the world level for years to come.. Nope. I have no idea of his mental makeup or if he even enjoyed running, but for me he had an incredible gift and just quit. So not a fan of him at this point.
Dathan had some success at all levels. Highschool, then in college team and individual xc champs, pro half marathon and xc bronzes, making Olympic team. He was my least favorite at the time, but he had strung together the better career in my opinion.
