Lol come on man they aren't even comparable. In the sample size you're using Svech was a 2nd liner not scoring many goals. Dach doesn't even look like an NHLer. In 23 games Svech went to becoming a top line forward with his 23 points while Dach still stinks. Some people are doing carthweels because he wasn't a minus for the first time and hit a couple of guys which is considered a good game for some reason. It's hard to see how one of two actual offensive threats on the Canes in those 23 games is leeching assists off his linemates. Admittedly I didn't watch him for all 23 games but it just doesn't add up. Maybe for a very brief stint which to your own standards should be extremely hypocritical since it's less than what you're allowing for Dach. I did however watch Dach who was leeching off of Suzuki and Caufield in his successful season at a 53 point pace.
Because you mentioned Monahan for some reason. Hertl had the same injury as Dach.
But as I said, with Caufield he was still doing other things. Yeah he wasn't scoring goals which was annoying, but his compete, defensive game, and playmaking were a million times stronger than Dach's so far this season. Caufield going from a 1st liner to looking like a 2nd liner is nowhere near the same as Dach going from a 2nd liner to a healthy scratch-caliber player.
