I play Fantasy sports all year long, Baseball, Football and Hockey. I mostly use it for baseball because they have the best projected starting pitcher chart in the business. Besides accurate news they offer a variety of feature article, a Draft Kit, depth charts, cheat sheets (per year and per week), stats and a bunch more. See for yourself, rotowire.com.
If you play in a competive money league it's worth investing. If you play with no money involved, I wouldn't pay for it.
