I don't think points should be too heavily weighed when judging Frost or any other prospect because 1) usually they're not being put in a position to score, both when it comes to teammates and usage, and 2) scoring is so fluky in small sample sizes that someone can play well and not score and others can play like crap and score plenty.
For example, Frost was 11th in forward TOI per game last year, so people bitching about him not scoring much aren't being fair. How could he score if he's hardly on the ice? Especially when entire team as a whole couldn't score for shit. Plus, visually he looked really good most of the time. You could see his smarts and skill on display, even if it didn't get rewarded.
And in general it's more about how bad the vets are than anything. With someone like Thompson or Deslauriers, you know they're adding nothing of value to the team. At very best, they're treading water and surviving. If that's the case, I'd rather gamble on a guy who actually has skill and upside and just tolerate whatever ups and downs come with them. At worst, they're equally as bad as the vets. It's not like Frost, Laczynski, Allison, Brink, etc could be worse than someone older, slow, bad at everything, and won't get any better, like Thompson, Deslauriers, MacEwen, etc.
