Provorov has the required skillset. He is strong, can skate, move the puck, pass, shoot, hockey IQ. Imo all are above league average...some very very good, and others average or slightly above.
In order for Provo to continuously showcase these skillsets, he needs to be consistent. Consistency leads to better decision making, which leads to higher confidence....when these things happen, everybody will talk about him as a 1A dman again.
So why isn't it happening?? For me it's got nothing to do with his skillset or potential. He's got all the tools...it's his confidence and decision making. Most people need to be put in the right situations/environment in order for confidence to flourish. Whether it's a vet damn to lean on to take away some pressure, or coaching, or the (lack of) leadership, or whatever i have no idea.
Mentality, mindset, confidence, decision making is everything! Some guys, like Pronger, will always be on top of these....but most human beings need to be put into the right conditions for these to flourish. And these things usually require life experience. Provo needs help here, then the rest will follow.
By the way, replace Provo with konecny/sanheim/farabee/frost/Myers/Patrick and it's the same for those guys when it comes mentality/confidence.
