FF peaked many years ago. Now any casual geek who doesnt know shit about football can play and do well with all of the information available via 9,000 magazines and the internet. It wasnt too long ago you actually had to watch games, do your own research, and know what the fuck you were doing. Now you can just auto draft and do whatever ESPN.com suggest you to do, and do reasonably well. It's not nearly as fun anymore.
Fantasy baseball jumped the shark to some degree too, but is harder for casual dumbfucks to play, so it's back to being a better experience than football.
