Don't get me wrong, I think Ohio State is very good, but I'm just throwing out an example of another team that has played a very poor non-conference schedule. I don't hear people saying that they need x number of Big Ten wins to make the tourney since they played a weak schedule.
And to put it in perspective a little, OSU has 5 games remaining against ranked teams, none of which are in the top 10. UC has 7 games remaining against ranked teams, 4 of which are in the top 10. On top of that UC also plays Marquette, Louisville, West Virginia and St. Johns twice. Just an absolutely brutal schedule from here on out, but apparently people are all worked up over UC non-conference schedule.
