As always, some really good and fair comments on the NAIA and also some jelly-face, pimple-licking, childish jibber-jabber on the subject.
Obviously, the NAIA will have less depth, that's a given. Many of the top schools have gone NCAA II. That's a fact. It doesn't take a genius to know this, so I don't know the point, or the fascination of bashing the NAIA.
Like a previous poster said (HRE?)- the NAIA falls somewhere between DIII and DII.
It's also worth pointing out that probably 80% of NAIA kids never broke 2:00 or 4:40 in high school, so you see some massive improvements...and you know, every now and then there are even guys like Wieszorek (sp) that make a name for themselves. (he was a 2:14 guy in HS).
However, as long as there are old Kenyans that want opportunities in US colleges, the NAIA will always be tough up top. You can look at the results and see that yah, you have to be relatively fast to be a top naia guy.
Another thing I think you look at is that many of these NAIA coaches treat the national meet like the state track meet in high school and double and triple guys. For example, Kisorio ran 3:41 and 1:47 within about an hour...and on races #4 and 5. Because of the lower-depth in team dynamics, doubling probably is not a horrible idea if your team buys into it and you're trying to win a title.
For comparison-sake, I posted some national results below, which probably aren't fair to use, since championships are about place and not time (not to mention weather and altitude..div 2)....but I also don't think it's completely fair to look at performance lists, since most NAIA schools are midwestern and don't have budgets to fly to the big meets on the west coast that have now become essential in NCAA I/II to even make the national meet.
Most of the qualifying times come from small, nasty midwestern windy-storm meets where you have to solo or make deals with coaches/athletes to trade leads, etc. to post fast times. Run the 1500 solo in Olathe, Kansas at high noon in 25 mpw wind or get pulled around at Mt Sac in runner's paradise...which QT is going to be faster?
