First of all, I was responding to a post that says "He produced last year without Panarin" which insinuates that his level of production last year wasn't that different from this year - which obviously isn't the case.
Re: February onwards. Even if we just talk about the final 28 games of the 2018-19 season, the most generous sample possible, Strome still only scored 1.6 5v5 P/60. For comparison he has scored 2.77 5v5 P/60 with Panarin this season. He did increase his production overall, but it was mainly due to getting a prominent role on the powerplay and shooting 40% on it.
I'm not saying he isn't playing better here than he did for the Oilers, he obviously is. I'm not saying he hasn't been great with Panarin, he obviously is. All I'm saying is that he hasn't been more productive than a middle six player away from Panarin at any point of his Ranger tenure and that it needs to be taken into account when deciding whether to extend him or trade him. As long as it doesn't hinder us from giving DeAngelo a long-term extension I'm all for signing him to a 1-2 year deal, since I'm a big believer in "if it works don't fix it".
