This is a tough hire for Ohio State. Day has been just about as successful as Urban Meyer but loses the wrong games. There is probably only a handful of coaches that would be satisfactory for them to pick. I think they would have to have someone in place before pulling the rug out from under Day. They won't want to get rid of him, before having his replacement in place. This isn't a job that is just going to be opened up to everyone. Vrabel probably at the top, Marcus Freeman, OSU alum and has shown at Notre Dame that he could be successful. Urban probably still has the chops for 4-5 more years, Fickel would have been a good possibility, if he hadn't had the disastrous interim year before he was ready for the big time. Doubt they would trust him, but his success at Cincy was stellar. I think all four of those would be ahead of Campbell.
