I'd like to think the perception of the B1G as a weak conference will change. Last year certainly helped with OSU winning the NC, but it will take more than that to really change the image. Other than OSU, and to some extent, MSU, the rest of the B1G has been less than stellar, including Wisconsin, who finally won a bowl game last year. The SEC has depth in terms of the number of really good teams as well as the talent. At the very least, the B1G East will be a force. Chryst and Riley...time will tell.
Give Harbaugh a couple of years and Michigan could be seriously good; ditto for Franklin, although I'm not sure just how good he is as a coach - he can definitely recruit.
The trend is definitely in the right direction. Some of the other programs in the B1G Ten, whom are about to get a big payday when the next TV deal is finalized, need to step up to the plate.
