The NAIA actually looks pretty strong individaully even compared to the NCAA. Take a look:
Boit, CMU: 13:17 5,000m in Europe '01
Tighe, Minot: 77th in '02 World XC 12k (#1 Canadian ahead of US's 4th and 5th), 13:50 to win Penn Relays
Araya Haregot, McKendree: unknown Ethiopian supposedly as good as (or carried jock strap for) Kenenisa Bekele, double '02 World XC Champ
