I agree that no one respectable has said OSU would only win that many games but....
I live in North Louisiana and the day Braxton got hurt I was listening to the local sports radio station. On the afternoon radio show, where they have the local "sports experts" take over for 3 hours from ESPN radio between 3-6pm, they lit OSU up for the entire time I listened. They did not say that OSU would only win 3-4 games but the majority of the commentators and caller comments were that OSU would finish in the middle of the B1G's East division. Next they said OSU would finish in the middle of the pack in the SEC even with Braxton, and that OSU would finish in the middle of the pack, at best, in any year. (which they all agreed on) Then they said that OSU would still have a decent record only because OSU never leaves the state of Ohio in the non-conference. They mentioned that for the last 7yrs. the local morning show (which I personally have not heard) they have called the OSU non-conference schedule the "see Ohio tour". The reason being that everyone either comes to Ohio to play OSU or OSU plays 2 Ohio schools, 1 usually an FCS school. They went on to state that none of them (there were 4 commentators on the show) could ever remember OSU beating a good team on the road. Then the 2 younger members of the "panel" stated they had never seen OSU beat any of the good teams, ever...that OSU always loses against good teams (at least the 2 older members said that OSU has "on occasion" beaten good teams). There was much open laughter by all involved while they said these things.
At that point after listening for approx. 45mins of the show (yes it went on at least that long) I shut it off. True story.
I don't know who the twitter poster was listening to, but I have no doubt he heard it.
Make of it what you will.
