Caps fan here who has a second team now in the Canucks as Holtby is my all-time favorite player. I don't think Nucks fans know what they are getting in Holts. Because of the Caps' success, and Holtby's numbers in the last few years, the idea has been that he's not that good anymore. That just isn't the case. Braden Holtby is a fantastic goalie. The Caps, as much as I love them, have TERRIBLE defense. Like really, really, REALLY bad. The best defenseman, John Carlson, isn't really that great (despite the hype). He's a better offensive player than a defensive player. The Caps have atrocious defense. It's so, so, sooooooo bad. The offensive prowess of the team, and, yup, Braden Holtby managing to keep the team in the game so that the offense could come in and do their thing and win the game, is why they are successful. (There's a reason that the Caps had the most comeback wins.) Of course, what this did is decimate Holtby's numbers and make it seem like he was doing a lousy job. He was not. He was just being hit with high danger shots left and right (for the last 5 years he has been in the top 5--generally top 3--in that statistic, Holtby's net is pretty much always a big, angry red blob!) and essentially being left out to dry on a regular basis, night after night by his team.
As for their new goalie, Samsonov, doing so much better? Well, as good as he is (and he is good), he faced easier teams, the team helped him more than they did Holtby (because as they said themselves, they knew that Holtby more often than not would save their butts), and the other teams didn't have tape on Sammy. As the season wore on, Sammy's numbers did drop--he still did good, he is really good--because his weaknesses were being exploited now.
My point here is that Holtby is a great goaltender who suffered behind REALLY horrible defense that was disguised by fantastic offense, and his own great goaltending that was disguised by his horrible numbers that were there mostly because of that really, really horrible defense. I've heard from other Canucks fans that the defense is bad on this team, but you've got Jay Beagle (former Cap who the team sorely misses STILL!), and now Schmidt who is great (another former Cap who was only beginning to shine in D.C. before Vegas got him in the Vegas draft). Even with those two, the Canucks defense is better than the Caps, and I don't know what your other defensive players are like, but I'm sure you have some other good defensive players. And whatever your coaching situation, it can't be as bad as Todd Reirden. Reirden was HORRIFIC! Terrible, awful, just bad, bad, bad. So, so, sooooooooooooo bad. And before he was the head coach, he was the defensive coach. Clearly, the former head coach, Barry Trotz did his best to mitigate some of the worst of Reirden's issues, but he could do only so much since the Caps' head office was so gung-ho on Reirden.
Bottom-line, ignore the terrible numbers and people who didn't watch every game and only paid attention to numbers, Holtby is a great goaltender. The Canucks are lucky to have him.
