This happening had actually crossed my mind since it kind of made sense. -GS could have probably come back to RU but he turned up his nose and showed little interest, (from what I read RU wasn't a big enough "name" for him any longer), then he gets stiffed on every HC opening he was interested in, and as result, because of his relationship with Urban Meyer, he slides into the vacant DC position at tOSU with the idea of rebuilding his image in order to eventually land another college head coaching gig.
Like some others have mentioned though, I don't view this as some sort of cataclysm. tOSU is one of those programs that can recruit on its name alone, (of course, it also helps having one of the best HC's in the country at the helm). They recruit nationally and just like everybody else, they can only take so many players, and GS being there isn't going to change that. -And our new HC strikes me as being a guy who doesn't back down from anyone in recruiting, and Schiano possibly being on tOSU's staff isn't going to make CA run away and hide either.
