To me, there's a big pool of people that can qualify and who does in each event depends on who decides to try to triple or what combo they do. I think it's easier to outline who the essentially locks are, strong chances (like greater than 50/50), and outside chances. I'll do guys and then girls a bit later today. These aren't in a particular order.
800:
Locks: Stadtlander, Kemper, Helder, Blaser
Strong: Heemeyer, Reed, Lucas, Stevens, Ringert, Sheesley, McOmber
Outside: Ryan, Marlatt, Reed, Janecko, Carlson
1600m:
Locks: Stadtlander, Kemper, Helder, Blaser, Heemeyer, Ringert
Strong: Lucas, Sheesley, B. Jensen, McOmber, Burdick, Stevens, S. Jensen
Outside: Reed, Marlatt, Ihmels, Tuft, Orton, Antonnen
3200m:
Locks: Heemeyer, Ringert, Lucas, Sheesley
Guys that are locks IF they run it: Stadtlander, Kemper, Helder
Strong: Tuft, S. Jensen, Antonnen
Outside: Ihmels, Burdick, Taggart, Hymas, Donahue, Dodds, Richardson, Kurtz, Thomas, B. Jensen
The 3200m is an interesting case where guys who qualified last year have been leaped by guys like Antonnen, Tuft, and Sam Jensen. Maybe Burdick and Ihmels are closer to the strong side of things and are if Stadtlander, Kemper, and Helder don't run the 3200m.
As a bonus:
4x800:
Rocky, Boise, Centennial, Timberline, Eagle, Mountain View
