Because there's no competition in your conference
Ohio St is 20-23 all time in bowl games. If you only want to look at somewhat modern history, you're 9-13 since 1990.
It's Ohio State M.O. Roll a weak B10, lose their bowl game to a more athletic team. To be even more specific, you're 1-9 against the SEC in bowl games since 1990, the only win being against Arkansas by 5 points, hardly an elite team in the SEC.
This is an absurd argument. Skill of current players and coaches only determines team strength this year. There is no doubt Ohio State has weaknesses, but you have no grounds to state that OSU will in the future 'lose their bowl game to a more athletic team' by your own admission. By your own admission, 'Ohio St might actually be good' in previous post. We will find out in the Rose Bowl this year most likely. You cannot both make the claim OSU is/will be a weak team and also make the claim that we can't know how good OSU is based on the schedule. If you don't understand, google 'law of non-contradiction.'
This is not 2006; Jim Tressel is not the coach and Troy Smith is not the quarterback at OSU. In 2013, betting against OSU is betting against Urban Meyer. Are you making the argument that Meyer will not be able to recruit great athletes at OSU? Are you making the argument that Meyer will not be able to coach his players up to the same level at OSU as he did at Florida?
Investigating your claim 'the only win being against Arkansas by 5 points, hardly an elite team in the SEC':
Arkansas in 2010 was 6-2 in the SEC, beating Georgia, South Carolina, Mississippi State, and LSU, and losing to Alabama by 4 and 22 to Auburn (the national champion). I argue that in fact Arkansas was an elite team in the SEC in 2010, when they were defeated by a typical OSU-Tressel team. Incidentally, the same could be said of the 2009 win against Oregon. This is the most recent reliable data available, considering what happened in 2011 and 2012.
Investigating your claim that OSU has more BCS wins than the entire ACC, and the most BCS wins 'Because there's no competition in your conference'
If the Big10 truely had no competition, you would expect OSU to typically lose BCS games to teams from other, presumably more competitive, conferences; they typically do not. Your argument fits no facts, only your irrational bias.
Having read your posts to this point, it seems like repeating the same unsupported assertion many times constitutes a valid argument to you, so long as you see others repeating the same assertion (say, on ESPN), and the assertion fits your bias. Facts, like, "OSU/Urban Meyer win a lot, including in BCS games against quality opponents such as 2010 Arkansas and 2009 Oregon" don't seem to matter to you as long as you can repeat something you heard someone else said like 'teh bIG10 is weak!'
