I think everyone is happy. I think everyone is grateful. Desiring improvement at whatever level you are performing is the best attitude any winner can have. It is what makes Alabama so dominant.
I think desiring improvement while undefeated is the sign of a very good and mature fanbase and attitude. Trust me, the coaches and players desire improvement even though they're undefeated.
Enjoy the wins. Winning football is hard, but never settle. Always improve.
