Switzer is the type coach that Booger would have wanted to be if he'd followed his heart instead of his mind. His hunger for money and to make it big was the driving force but he longed to be a coach just like Switzer.
There are task oriented coaches and there are relationship oriented ones, just like managers of companies. Switzer was all about the relationship and he was buddies with Booger and Jimmy when he coached them and they responded to him because they were self motivated and they wanted to please their coaches.
Jimmy was more task oriented and really didn't care about the relationship unless you earned that through accomplishing his tasks. That's why he said he treated all the players the same.........differently.
There's no better way to be because both ways work and fail. Campo was relationship but didn't have the talent and his boss was stronger on the relationship with the players' side. That's why Switzer was on his short list along with Jimmy but he knew Jimmy would make the tough calls a lot easier. He made the right hire because Switzer would have never considered trading their best player, he was all about recruiting at OU. And he was a damned good one. He was as effective at schmoozing parents as the players.
Switzer had been the other candidate on that short list and no other was considered after one that Booger considered to be a friend turned on him. Switzer was the logical choice to caretake the team and smooth things over for Booger. He knew exactly what he was getting and Switzer said it coming in, "they're adults, I'm going to treat them that way". He also considered it Booger's team, not his own. The inmates were getting a doc that was as looney as they were. Think they didn't get a kick out of Barry packing heat on a plane?
