There are a lack of programs that can sustain success as a Top 25 team, let alone a top 15 team for 3-5 years. Seriously, Ohio State is the only lock for this list. Sparty - there is potential, and they probably have the highest 5 year trajectory of any other team in the conference. But again, can they sustain the success? Nebraska and Wisky have good arguments, but I am not sure if these two are consistently top 15 programs. Pelini is seems to always be getting himself into some sort of trouble, whether its on or off the field. You can make an argument for Penn St, but they have a lot of work to do but they have legitimate upside. Michigan - what is going on up there? They are in bad shape.
Who are the top teams for the next few years? I do not see how this conference is going to make notable improvements throughout and become competitive. Not too many are even close to keeping up with Meyer
Simply put, these programs have almost not shot of sustained success: Purdue, Indiana, Rutgers, Illinois, and Northwestern. Minnesota, Maryland, and Iowa, well the jury is still out their future identities and if they can turn out winning seasons consistently.
