I'm gonna come out strongly and disagree with almost everyone here.
Yes Broncos have Carrigan, Haas, Walsh etc but that's not the reason where they got to where they are.
The main reason imo is $$.
If Madge thought Carrigan needed to become a better leader, he'd have gone to the Broncos board and said here's a leadership coach that costs $200k a year, let's hire him to better our leaders. If he went with the same proposal to WT board, he'd be laughed out the place.
So much work is done on continuing education of coaches and players, it's insane. Many clubs spends hundreds of thousands if not over a million dollars more in educating coaches, players, psychs and performance staff that we simply don't have the money to spend.
The notion that Madge can coach elite players but no average players is BS too. They had players like Isaako, Neame, CNK, Papalii etc who I wouldn't class elite. Current broncos had guys like Hetherington, shibasaki, the two singers, Walters etc who had their best year.
To get the best out of a team, it takes a hell of a lot more than one good coach and talent/ skill. There's so much more to elite sports than that. USA constantly wins more gold medals than African counties, would you say the Africans have less talent that uSa? No way. And if you put the head coach of track and field of USA in the Kenya team, would they win 50 holds? No way.
To me, the main contributing factor to Madge "failing" with us but not with NZ, NSW, souths and Broncos is money. I'm sure there are other factors, but money has to be the biggest.
