I'm fine with this decision. I don't cry about Ovi and Sid refusing to go to the ASG in the past - why would I cry about Rask? Yes, I jokingly say they should be drawn and quartered for their refusal to show, but c'mon - it's a meaningless game, and these guys need rest. I think if you've done one ASG, you've done your duty to the fanbase.
If anything, Rask has shown that rest vastly improves his game. He's shown that he's good for about 70 games during a year. That means if you want him to be able to play 20+ games in a deep playoff run, you keep him in the 40s, which is exactly what we did last year.
The one thing I'm not a fan of: the suspension length. I think pitchers in MLB have different rules than position players for suspensions, right? I mean, they have to. Same should go for goalies in hockey - I wouldn't be opposed to the punishment for goalies being a suspension for both games on either side of the ASG, not just one. Rask being out for WPG means literally nothing - there's a decent chance he wouldn't have played that game anyway.
