Imo if we're going by overall most impressive performances, rather than hypothetical matchups or more holistic looks at overall season performances, I think it should go
1 - Aaron Sahlman @ NXN
2 - Leo Young @ Clovis
3 - Lex Young @ CIF or Kole Mathison @ Kinney/Foot Locker/Eastbay/Champs Sports
3rd is hard for me because on one hand Mathison has the better speed rating, and much larger margin of victory over a NATIONAL field. But then again Lex ran 3 seconds off a course record equally impressive to a course record Mathison was 17 seconds off.
5 - Hunter Jones @ NXR Midwest
On paper demolishing the course record at a course as ran-on and historic as La Verne Gibson by 25 WHOLE SECONDS should rank much higher, but when you look at how close Burns, Ackley, and Anderson were, guys who finished relatively low at NXN, and then you look at how fast the whole race was and what the speed ratings were you start to realize that maybe this was not quite as impressive was the previous 4 performances. At least imo.
