Lol. Anderson is a veteran of the game but despite being at this venerable stage of his career, his technique doesn't even match that of many NHL rookies. Anderson is on his way to retirement with subpar fundamentals. His position, technique, stance... everything is flawed and well below NHL standards. I'm talking about basic things like covering your posts adequately.
He certainly has some talent, instincts and he's a real competitor. But not nearly enough to compensate for his technique and also, not often enough, because he's really the hot and cold type, capable of highlight reel stops but also stinkers. This explains why he's been at best a plan-B type of goalie most of his careers, when he wasn't just discarded.
I don't hate him or anything. We were rooting for him in our household and are disappointed the Sens lost. I'm also not saying he is the only reason the Senators lost. But the Sens would be in a lot better position if they had a consistent, technically sound goalie and for now, they have covered Anderson's inadequacies by implementing one of the most successful collective defensive system in recent years.
I think Anderson finishes his career as an amazing #2 on a contender and wins a cup. But he doesn't cut it as a #1. Not enough to carry a team to a Stanley Cup unless it's loaded with talent.
