Perry (31-2) was sailing through an unbeaten season until an upset loss to Missouri's Todd Porter and a defensive pin by Minnesota's Logan Storley. But Perry has beaten Porter twice and Storley once to earn the top seed in a weight class that promises to be the most wide open of the tournament.
Gelogaev (24-3) has split with No. 1 seed Dom Bradley of Missouri but lost twice to defending champion and No. 2 seed Tony Nelson of Minnesota. The OSU senior does own a December 2011 major decision over Nelson before an injury prematurely ended Gelogaev's season.
OSU's hopes also ride heavily on its balance. Tyler Caldwell (30-4, seeded fourth at 165 pounds), Jon Morrison (25-6, seventh at 133) and freshman Alex Dieringer (30-2, sixth at 157), must finish near or above those positions to produce the necessary team points for Oklahoma State to win its 35th NCAA crown.
Chris Chionuma (27-8, seeded ninth at 184) and Blake Rosholt (14-7, 11th at 197) could earn All-American honors by slipping into the top eight and provide extra team points.
Oklahoma coach Mark Cody sacrificed a strong team showing this season by redshirting three All-American seniors: Jarrod Patterson at 125 and Wisconsin transfers Andrew Howe and Travis Rutt.
Howe was the NCAA champ in 2011, and Rutt an all-American. With that trio sitting, the Sooners qualified only five wrestlers for this weekend's tournament. Backing Maple are 133-pound eighth seed Cody Brewer (21-8) and sixth-seeded 165-pounder Bubby Graham (21-4).
