I guess I would have BP at around 5. You could probably interchange Kill, Fitz, BP, Hoke and Anderson at this point and put them in any order.
No, you couldn't. There's no factual basis for it. I'm not going to waste my time presenting the entire resumes of each coach, but just look at the credentials:
Franklin hasn't coached a single game in the Big Ten. His wins in the SEC over the last two years consist of Georgia (8-5), Florida (4-8), Kentucky (2-10), Tennessee (5-7), Missouri (5-7), Auburn (3-9), Kentucky (2-10), Ole Miss (7-6), and Tennessee (5-7). He might turn out to be a great coach, but being ranked at #3 isn't actually based on anything - it's a prediction. He should be an asterisk on the list.
Pat Fitzgerald has had losing conference records three of the last four years, and five of his eight years total. Bo owns head-to-head on him, and coming off his best season in school history, they were a field goal away from going winless in the Big Ten. I get that they don't have the resources, fair point. I also get that they don't have the expectations, not a fair point. Surpassing lower expectations doesn't mean you're a better coach than another who doesn't reach higher expectations.
Gary Andersen seems to be a solid coach, but that's after one season. For a while they were two plays (one the official's fault) away from being undefeated on the season, but then they got spanked by Penn State and beat confidently by SC. Not much else to go off of, but he seems like a good one.
Kirk Ferentz has a losing conference record over the last four years, and is barely over .500 lifetime. They had a good, not great and not even really good, season last year after going 4-8. So kudos for turning it around, but Ferentz is the coach that got them to 4-8 in the first place. Once again, Bo has head-to-head. Still have head-to-head here as well.
Jerry Kill has done....what, exactly? His team had a decent season, but he wasn't even coaching for 75% of it. Jerry Kill has a long and successful coaching career, but is 17-21 at Minnesota even considering last year's success that he only had a fraction of a part of. Bo has head-to-head and it's not really even close.
Brady Hoke had a good first season, but has failed to win his division even once, and instead of getting better his teams have gotten worse, going from 11 wins, to 8 wins, to 7 wins. With all the resources in the world, and with the best recruiting in the conference, Brady Hoke has done next to nothing. Bo has head-to-head on him, and also made him look like an absolute fool in his own house.
