Very few champs come from outside the top 15 and most are top 10.
Over the last 8 years, 47.5% (38/80) of the NCAA champs were ranked as top 10 recruits, 61.25% (49/80) were ranked as top 15 recruits, and 38.75% (31/80) were ranked outside of the top 15.
Outstanding data, mrh, although the higher end recruits are beginning to win more often.
Over the last five recruiting classes, there have been 15 NCAA winners and 12 of them were ranked top 15 in HS. And 8 of those were top 5. Only 3 guys ranked higher than 15 have won titles.
My point is that these rankings are ID'ing future champs better than before. While not absolute, to have any chance to win team titles, you have got to load up on top five, ten, and fifteen talent. PSU and O$U are.
"Very few champs come from outside the top 15 and most are top 10" and "the higher end recruits are beginning to win more often" just aren't true statements.
mrh's stats above are accurate, I'll take the same years and look at it from a slightly different angle.
Of the 80 National Championship honors since and including 2010 (8 years), there were only 54 different individuals winning those championships. Counting Dake and Stieber 4x, Ruth, Dieringer and Ruth 3x, and 14 other guys with 2 championships...double, triple and quadruple accounting skews the data. Again, mrh's data is great, this is just adding to those stats. Note that the starting point is 2010, so data prior is not considered.
Of the 54 individuals;
-- 22 were top-10 recruits (40.7%)
-- 32 were not top-10 recruits
Of the 3x or 4x champs (Dake, Stieber, Ruth, Dieringer, and Cox), Dieringer (#15) was the only one outside the top-10.
Of the 19 individuals with multiple championships during these 8 years;
-- 10 were top-10 recruits (53%)
-- 9 were not top-10 recruits
-- Among the REPEAT champs, there was a #49 (Tony Nelson), a #73 (Gabe Dean), and a #75 (Jesse Delgado) ranked wrestler
13 of the 54 National Champs in the past 8 years (24%) were outside the top-50 recruiting rankings; (in order, from lowest to highest) #53 Houdashelt, #54 Simaz, #65 Gadsen, #66 Garrett, #68 Molinaro, #73 Dean, #75 Delgado, #88 Brown, #94 Burroughs, #176 Bosak, and not-rated guys Zabriskie, Robles, and Maple.
-- In 2011, five of the 10 champs were ranked outside the top-30 (#34, $42, #46, #94, and not-rated)
-- In 2012, four of the 10 champs were ranked outside the top-40 (#49, #54, #68, and #176)
-- In 2015, four of the 10 champs were ranked outside the top-50 (#53, #65, #73, and #88)
Not throwing shade on the benefit of recruiting blue-chippers, not at all. Opening up the data to include All-Americans would (imo) show a slightly better correlation to rankings coming out of high school. That said, it's still imperfect.
Recruiting a wrestler for their "fit" into the program, among other things, is a variable that can yield results.
