Just so much wrong here, and proven wrong over and over again.
"Fit" is a made up, hand-waiving variable that your cohort introduce to account for when a supposed recruiting hotshot comes into a program and falls flat on his face. Brewster, et al. "Well what do you mean, he was supposed to be a great recruiter! I thought that's all that mattered??" "No no no, you also have to take into account 'fit'. Brewster didn't work out because he was a bad 'fit'. Yeah." "..... well what does that mean?? Why was he a bad fit?" "Well obviously he was a bad fit! He didn't win!"
Another great current example is Iowa St vs Kansas. Iowa St went the correct route, IMO, and brought in a MAC coach that had a great run. Kansas, on the other hand, hired a hotshot recruiting coordinator from Texas A&M, as he promised to deliver the state of Texas to the Kansas football program and turn them into 1997 Nebraska.
Guess which one is winning out?
