By the within-7-point standard, we should arrange to barely win every time we play a stink team.
We could end up ranked #1 in that ranking. #1
Not true. If you let a bad team stay close, they often will beat you, just as, when a better team has let Ohio stay close, Ohio has often beaten them. As an example, consider the Pitt win in 2005. Pitt was no doubt the better team, but Ohio was scrappy, and stayed close, and then found a way to win. The Illinois win was probably the same - Illinois had more talent, but Ohio wanted the win more, and got it. As a contrast, the Penn State game was not within 7. Ohio was the better team, and pulled away at the end, ending any chance of a Penn State comeback.
There are certainly some examples of close wins over bad teams. The win at NTSU comes to mind as an example of that. There are also many close wins over some pretty good teams, such as Utah State or Pitt.
Considering that the core philosophy that Solich has built the program around at Ohio is to be relentless, and never give up, is it surprising that his teams have mostly been battlers that scrapped, and often found a way to win? I wasn't expecting it to be as good as it has been, but I did expect he was over .500.
Getting the discussion back on track, 2015 has a few games that are likely to be wins, but has at least 7-8 games where the point spread will likely be under 7. If the 2015 team is as scrappy at the 2009 team, and goes something like 5-1 in close games, it will be a very good year. If, on the other hand, they are like the 2007 and 2010 teams, and they lose more close games than they win, we may see a year that isn't up to our expectations.
