Regardless of the Kolzig/Oates stuff, whose impact I think is actually being overestimated, Holtby's tendency to get rattled and let himself feel undermined by certain things has always been his biggest problem. The flip side of that is that his play is particularly outstanding when his confidence is high, and I think he's smart and poised enough overall to learn to overcome the mental issues over time. Coaching that legitimately hinders his play by asking him to physically do the wrong things is obviously a problem that has to be addressed, but in terms of its impact on his confidence he needs to deal with it. Maybe the organization has jerked him around a little bit, as someone said yesterday, but too bad. All he can control is how he reacts to that, and to this point he usually hasn't reacted well. The talent is there and I think he'll get past this kind of stuff in time.
Separately, the overreactions here tend to verge on absurd, even putting aside some obvious posters who have personal agendas against him. Writing him off as Jim Carey is beyond premature and just crazy.
Another related thing that's interesting to think about is how the team's psychological weakness overall may relate to him. In a few instances we've seen downward spirals where it seems like the team and the goalies are simultaneously blowing games, mainly during the longer losing streaks. It's easier for a goalie to get rattled when the team around him is disorganized and mentally fragile. Obviously that goes the other way too, but it's worth considering how having a real coach and a team with the slightest hint of mental toughness might help Holtby deal with his issues better, or at the very least provide stability.
