I agree Ohio State deserved to be in last year. I also agree Alabama's resume is flawed this year.
BUT, again, this is a classic case of selectively highlighting the worst parts of Alabama's resume while ignoring the obvious flaws in Ohio State's (or whomever one thinks should be in ahead of Bama). Alabama lost on the road to Top 10 Auburn by 12 points. Ohio State lost to unranked Iowa on the road by 31.
Whether the committee is influenced by perception from past years is irrelevant. Neither Wisconsin nor Ohio State has any case that their resume is better than Alabama's. Keep in mind, too, that Alabama opened the season against #3 Florida State and won. Had FSU's QB not gone down for the season, who knows how FSU's season would have gone. You can't fault Bama for that. They scheduled a Top 5 team to open the season.
