No one team in the B1G not named Ohio St has been able to beat 'Bama, Georgia, or Clemson. Auburn and several other SEC teams have. Michigan has been weak. Penn St has been weak. Nebraska has been weak. They ALL used to contend for national championships. Now they generally lose to Ohio St. The B1G is weak outside of Ohio St, just like the ACC is weak outside of Clemson. And BTW, are you too young to remember how we used to beat Notre Dame on a regular basis? We played them every year.
The point of improving the overall level of the conference is to get the top tier talent wanting to play in the B1G. Why would the top talent choose the B1G when they could play in the SEC? You don't seem to get that...
