Here are the top returners from last year's NCAA XC champs. No doubt some may for whatever reason not run this year and jc transfers and new freshmen will be in the picture as well. All of these guys were within 1:15 of Cheserek last year, within 50 seconds of 4th place, and within 29 seconds of top 20, so any of these guys could rise a lot higher in the rankings even with relatively little improvement relative to the others.
1 Edward Cheserek SO (class as of Fall 2014) Oregon 29:41
4 Futsum Zeinaselassie JR NAU 30:05
5 Jim Rosa SR Stanford 30:08 (and his brother who is usually faster should be back after injury)
6 Stanley Kebenei SR Arkansas 30:10
8 Ben Saarel SO Colo 30:14
9 Patrick Tiernan SO Villanova 30:15
12 Trent Lusignan SR SD ST 30:18

The sophomores in particular would figure to improve a lot with a year of college training under their belts.
