They all have their strengths and weaknesses. I think I like dobber the most at this point because of the advanced Statistical outlook. I would say make your own but supplement information dobber provides on advanced stats. THN is ok. Fantasy hockey standard is ok. Yahoo is ok. Espn is a horrible joke.
well depending on the league you are in you might be better off making your own spreadsheets. most leagues tend to favor the goalscorers as they should but in deep leagues with multi stats like blks PIM and hits etc i prefer to look at the grinder guys that dont necessarily score big on the hockey previews.
so know your league and check out some magazines first i would say before committing to a site
I like the Forecaster as well, don't know if they make the best predictions but they easily have the best format. As an expert pooly I don't really care about projected point totals, rather I take last years stats and try to look at how the player will fit into his team this season. So something like The Hockey News Pool Guide lists all players in alphabetical order or something like that, with a brief blurb on how many points they may score. The Forecaster goes team by team and gives more of a mini scouting report on what each player does for their team. That's far more valuable information in my opinion.
Oh, and taking a quick look at the free guide above, looks like they do things the same way.
