I agree Bo needs time. And if nine wins and being in the hunt for the conference title every year is his ceiling for the next few years, I can live with that.
What most people are grumbling about isn't just the fact that he hasn't gotten it done, it's that too often when the wheels fall off, they REALLY fall off. Three times in 2012. Three times in 2011. Twice in 2010. Twice in 2009. Those losses weren't just losses, the team looked inept, completely unprepared to play winning football.
And it's not getting better, it's getting worse. UCLA, Ohio State and Wisconsin last year. Wisconsin, Michigan and South Carolina the year before. Those six losses were abysmal in the way the team floundered about, especially on defense, which is what Bo was brought in to fix. Callahan got fired for fielding an historically bad defense. Bo's job was to fix that, and he did for a couple of years. But it got worse in 2010. It got worse again the next year, and last year it was as bad - at times - as 2007.
The argument that Bo is developing talent is interesting. I'd like to see who Bo has developed from raw into something superlative. The quickest, most obvious answer is Ndamukong Suh. But who else? Matty O'Hanlon? He was decent, but hardly an impactful talent. I'm not seeing that angle of this.
I'm willing to give Bo time, but I'm not willing to completely turn a blind eye to the problems we have.
