If advantages are all it takes to win 9 games each year, then tell me why only 5 have done it. Are you truly saying NU has infinitely more resources and/or advantages than anyone else? I am not sure what to think right now, Knapp's post was as close as I can come to explaining my feelings, but trying to mitigate a fact that only 5 out thousands have accomplished is like spitting into the wind. The bigger issue in my mind is how the heck does a Coach who is good enough to accomplish the rarest of feats have such a poor side to his record as well?
They aren't
all it takes; obviously Bo Pelini is at least in part responsible and successful for his own accomplishments. For example, an orangutan could not coach this team to 9 wins.
To answer your question as to why only 5 have done it, because it is a needlessly restrictive parameter that works in his favor. Think about it:
First, you rule out any coaches that had to start their careers at lower schools, such as Les Miles, Nick Saban, Urban Meyer, Jim Tressel, Mack Brown, Bob Devaney, etc.
Then, you don't give them any room at all for a growing pain season. Bob Stoops and Pete Carrol both had one of those right before winning championships, for example.
After that, you weed out any coaches that haven't coached at least 7 years, such as Chip Kelly and David Shaw, and also coaches that coached long enough to finally hit a bump in the road, like Mark Richt.
You also leave no room for coaches who have took perennial doormats and made them contenders, like Mark Dantonio, Bill Snyder and Gary Patterson.
You also get to use 9 as an arbitrary win number, even though not all 9 win seasons are equal, and some coaches can go 9-4 and be unranked like 2013 Nebraska, and others can finish 9-4 and be #13.
Don't forget if a coach wins 9+ wins in 7 out of 8 seasons, but the one time he didn't was in the middle, then he doesn't count towards that statistic either.
