Dave, I know you love hyperbole and I love you for it but.....
Frank is the figurehead of a team of people. Mainly the team and coaching staff (of whom Dunc is the best... Don't bite).
Frank alone is not the Messiah.
I reckon they're the difference, or will be. The group, the coaching staff as a whole. And as we've seen / been recently, we're all working much better as a collective. Amazingly, you included.
Frank and his team (with more time) will improve the players we have (those that want to be here and have the right mentality - well done Anthony and Alex btw.). Hopefully buy well, within a collective structure (board, dof) and be able to implement their playing philosophy over time.
It's not always about the individual.
