This is exactly right in my opinion. He has really grown as a coach. To the point where he gives you that feeling that "Everything will be ok because Coach knows what he's doing". But it took him awhile to get there.Get outta here with a reasonable opinion like that!
You know what Collins did? He did what good leaders do, especially those who have had past success before their current difficulties. He took in those criticisms, looked inward, and made the changes to himself and his organization needed to improve. Those aren’t just simple changes, they involve working to develop oneself. He’s a better coach today than even last year. He’s coming into his own, and it didn’t happen on accident.
He got knocked on his ass after the first tourney and to his credit he changed himself. It took too long in my opinion but he did it whether that be hiring the right people, coming up with an identity and creating a great culture.
Some will say he's always been a good/great coach but I would say he's gone from a mediocre coach to a good/great coach. All the credit in the world to him for making the necessary changes so far into his career which is not easy for any leader to do.
