What websites do you use in fantasy football and definitely okay to list paid sites that you think are worth the money.

Background - I see two main areas of focus: Draft and In-Season help. My league uses CBS Sports Fantasy Football which we like.

Draft: what websites provide the right strategies to build your team? Which ones are good at player rankings.

In-Season help: this is one area I need the most help. Like most guys,  I wrestle with determining who to start and who to bench (for example: my RB's this week are Zach Charbonnet, Brian Robinson and Jamyr Gibbs.....wtf?). 

I like Yahoo sports fantasy coverage...any others.

I'm intrigued by the pay sites. Has anyone used and would they recommend any?

* I saw for the first PFF's fantasy help advertised today. Here's what they tout: 
In-Season Fantasy Tools: Tap into PFF’s award-winning rankings, Start/Sit Analyzer, positional matchups, and more to help push to the playoffs.
Mock Draft Simulator: Shape your favorite team with the industry’s best NFL Draft Tool.

$120/year ----- my fantasy league with 12 teams pays $1,700 to the winners, ~$700 and $300 for 2nd and 3rd place. So I'm tempted.

ESPN premium fantasy football site is advertised everywhere. Anyone use it?
