Ultimately, I guess it boils down to what your expectations are for the 2018 Ohio State football team. Mine are as follows: win as many games as possible before the end of the season (hopefully all of 'em, but I'll take two) with the Big Ten championship as a potential bonus, but either way, don't worry about the College Football Playoff. Spend a month learning not to suck in various areas in which Ohio State currently sucks a lot. Roll into the bowl game and utterly kick ass.
And that's it! So while I'm not okay with a five point home win over a bad (albeit improving) team, at this point in the season it doesn't surprise me.
