I am not very sure.
I think maybe he doesn't have the steel inside him to be that successful.
unless you are pinball, you cant be smiling and such all the time. HC is serious work.
Most of the best coaches have that steel in them, such as Mathews, Buono, Huffnagel, Austin, etc
Even Mike Riley had some steel although he had some pinball in him as well.
Paopao didn't have enough, he was just too nice and mild mannered.
