To some degree I agree, for one, Kevin was not a great coach and your right in that culture alone will not win football games/Premierships, otherwise, we would have won a lot more than we did during our golden years. But, the facts for our club are Folkes, Anderson and Gould, all ex-players, are ironically the last three coaches to bring home a Premiership.
At the end of the day, to win a comp, it's a combination of a lot of things including having an element of luck.
Agree, we don't necessarily need an ex-player to achieve success, but I think right now, we need that pedigree back in the club to re-set our identity.
