My two cents probably is worth about that much, but here's my opinion. I think "duck" matches are a bane to the sport from a fan's perspective. Of course we all want to see premium matches ike Starocci/Griffith or Fix/Crookham, but we're being selfish aren't we? Crookham has never wrestled Fix before and has rapidly improved in the last year. Fix is about the same as he was last year prior to NCAAs. Why should John Smith let Crookham test himself against Fix at this point? Fix is a tricky guy to beat and Crookham probably has never wrestled anybody exactly like Fix before. The less experience the rapidly improving Crookham gets against Fix, the better from John Smith's perspective. OSU only get's Fix's points at NCAAs one more time. I certainly like Fix's chances better without Crookham having experience against him.
Regarding Griffith/Starocci, Griffith barely beat PSU's 2nd team guy, Barraclough. Barraclough is AA strength though (in my opinion). I can understand a coach holding out guys in dual meets, especially when a team is so superior to the other that you can put in one of your reserves to get a little mat time. Perhaps Cael didn't see the point of Griffith/Starocci for one reason or another but saw a lot of upside for one of his better reserves to get a some Big 10 experience agaisnt a tough opponent. I know if I was a coach with a great wrestling team that I'd be putting in some reserves whenever I had the opportunity, that would help keep the wear and tear of the starters down until the important tournaments at the end of the year and get more experience for reserves, especially ones destined to be starters next season.
Probably most of the time the wrestlers actually want to wrestle the other guy and sometimes maybe they are a little too brave for their own good, and the coaches are protecting them by making them sit (unlikely, most wrestling coaches are sadists). Sometimes it's probably for seeding purposes, sure, but I doubt the wrestlers are making the call in those situations.
