7 wins, yes, yes (if Pelini could not coach us back into a playoff team each year, no other coach in the $300k salary range would).
If he could get 7 win and a deep run in the playoff, he wiould go else where as a head coach. If he could not make a deep run in the playoff, he would go else as DC. Either way, I think he will be gone next year.
Who knows, Tressel might talk him into staying.
