I do not think you can fairly compare coaches today against coaches from the distant past. Old time coaches had to be perceived as tough (Bryant) or smart (Dodd) and be in charge . Todays coaches are managers and businessmen and have to deal with much more sophisticated Xs and Os, have a lawyer on retainer, avoid the PC police, pander to the media or be very media savvy, and deal with "entitled " players and parents, not to mention what is in their closet is instant news, real or distorted. Yesterdays football savvy "good ole boy" can no longer survive as a head coach, or even be employable.
