I strongly disagree with the idea of Ohio State being fine in terms of recruiting. Cooper's downfall was directly tied to his complete unwillingness to recruit in-state; it's not like we have 720 high schools that play football or anything. He couldn't beat Michigan, who regularly poached Ohio-bred talent (Desmond Howard and Charles Woodson being the most obvious). He was perfectly fine letting local kids walk away and go elsewhere, as long as he could reel in the kids from Texas, Florida, and California. We're not talking about one-star and two-star guys, we're talking about four- and five-star players. Antonio Hall, from one of Ohio's most storied programs, went to Kentucky and was a four-year starter. Na'Shan Goddard went to South Carolina and was a four-year starter. Michael Munoz went to Tennessee and was a four-yeaer starter. These are just three linemen, and all came out of Ohio within a two-year period and became four-year starters.
Part of the appeal of Glen Mason was that he was building Minnesota toward Big Ten contender status, but on the backs of the Ohio kids that Cooper didn't care about getting. He was getting elite athletes right out of the Columbus City League, right out from under Cooper's nose, and then using them against Ohio State. The rise of the MAC in the late 1990s was directly attributable to Cooper passing on the local kids, and seeing them go to places like Bowling Green and then into the NFL.
When Tressel got to Ohio State, he went out of his way to bring the high school coaches back into the fold. If a new coach was hired somewhere (anywhere), he was guaranteed to get a congratulatory card and letter from Tressel, along with a business card inviting the coach to call Tressel (actually, his secretary, but whatever) for anything football-related. It was a nice gesture, and plenty of coaches who'd been repulsed by Cooper appreciated it. It's the same stuff that Mack Brown had to do after replacing John Mackovic, who'd turned Texas from good ol' boy football into something derisively referred to as "The Tea-Sippers Club".
You weren't getting out-recruited by Miami of Ohio though. That's where we're at now.
