You have to pay to access most of this site, but they offer a 10 day full free trial here. They have a tool that allows you to input your league settings and it generates rankings based on them, and allows you to download an Excel file of them. Also feature nice writeups on how they arrived at each players rank.
Free site with tons of different lists and rankings. They have a custom ranking tool similar to Rotowire but they don't have the option of downloading an Excel file of them. ADP charts, sleepers, busts, players to take gambles on, handcuffs, etc. Very useful site with some good info and opinions you won't find anywhere else.
This site has unique rankings, in that they compile a ton of experts' rankings and average them out to generate their "Consensus" Rankings. Also offer sort of a Consensus ADP as well, as they average the mock drafts of 5 different sites.
Their Mock Draft Simulator is great too. It generates a random mock draft according to their rankings/ADPs in a fraction of the time a "real" mock takes to complete, and does so without the risk of a troll player being in the lobby.
Also offer some paid features like creating cheat sheets, exporting rankings, creating Excel files, etc.
You have to pay to get the rankings and "Draft Guide" that they offer, which I don't. Still, it's probably my favorite site both preseason and in-season, strictly for the player news/reaction blurbs that they have. I find myself on the site several times daily, checking breaking news alerts and searching for players I'm interested to see what's going on with them.
Hope everyone can cook in their drafts .
