Bo's "signature" wins:
2008 - maybe the win over clemson in the bowl game
2009 - MIzzou #24, OU #20, Arizona #22 (shutout). However; If we consider ourselves a top 25 team, then wins against rank 25-20 teams shouldn't be 'signature', although the shutout was impressive.
2010 - Okie State #17, Mizzou #7.
2011 - Mich St. #9, Penn St. #12
2012 - Michigan #20. again not sure win over #20 should be 'signature'.
2013 - none so far
So 2010-2011 were the best in terms of quality wins. 2009 we had a dominant defense but no offense. 2010 we still had a decent defense with a new explosive offense w/ freshman Martinez. Of course we all remember what happened at A&M, then against OU and Washington to finish off that season. I think the conclusion to the 2010 season was the turning point in Bo's career here (so far). We had been in the top 10 most of the year and then that A&M game kinda broke our backs. Sure we picked up a couple of quality wins against Mich St. and Penn St. in 2011, but wasn't the Penn St. win right after the whole Sandusky thing? The Mich St. game was certainly quality though. Regardless I think our confidence took a big hit with the way we finished off 2010, and our defense has been on a steep and steady decline since.
It is a bit hard to see some of our former Big 12 competition having a lot of success... A&M, Mizzou, Baylor, Texas Tech, Oklahoma St, Oklahoma are all currently ranked. I dunno what that says other than that since 2010 they've gotten better and we've gotten worse.
So.. where are we at now? Haven't seen a signature win since 2011. Michigan State is our only shot left this year during the regular season... post-season could provide chance(s). A win over a quality opponent in a bowl game would be good.. and if we somehow win out and made it to the B10 championship game and somehow beat Ohio State that would be the kind of win that could turn everything around (and likely save coaches jobs). I'm not very optimistic though, I see us losing a couple more games, and getting a mediocre bowl opponent.
Assuming we don't have a miraculous conclusion to the season.. where do we go from here? That would be 3 years in a row without a 'signature' win whilst racking up a few 'signature' losses. I think Bo's non-coaching successes may buy him another year to turn things around (probably with a mandate of a new coordinator or two), looking a bit like Solich's 2005-2006. But, maybe he'll be gone at the end of this year. I think that will depend on the nature of Shawn Eichorst who is still somewhat of an unknown quantity. I don't think Eichorst is the type to pay much attention to the short bursts of fans' calling for Bo's job or to be eager to put his own signature on the program (ala Pederson). But, I also think that with the way this season has gone that there almost surely have been some feelers sent out to gauge interest. So it may come down to that. Does Eichorst feel the right guy is out there and available this year? Where does he fall in preference for a new coach? A nebraska guy through and through? A proven commodity looking for a place with a higher ceiling? A young up and comer from the lower ranks? A proven NFL guy wanting to take a stab at the college game?
Okay I've typed way more than I meant to lol. I'll leave you with this: we are still currently a 2 loss (1 loss conference) team. The rest of our schedule is still nowhere near as tough as we've seen in the past. How we finish is likely to have a pretty big impact on what happens. We could win out, I don't think there's much chance of losing out... but here's the key: 4 losses. We get there with 2 more losses + a bowl win, 1 loss and a bowl loss, or winning out and losing CCG and Bowl.
