I haven't played fantasy sports hardcore enough for a number of years to justify paying for Rotowire (the offer from What if was just 10 bucks off the membership/sign-up cost), so I can't answer on that one. I loved Rotowire when I was doing fantasy ball hardcore about a decade ago. I don't know if they still have the feature preseason where you can plug in the exact scoring system for your league and it re-arranges all players into a hierarchy of draft order designed specific to your league or not, but that feature alone a decade ago was worth its cost in profit.
