Ignoring whatever the hell happened in this thread, there's a few people here who are very knowledgeable on advanced statistics and analytics.
If what you're looking for is people who post tons of little generic fluff pieces on every player while trying to attach a SABR label to it, you won't find it here. We do quite often discuss various players and performance during the season though, as the situations present themselves. Those discussions definitely use everything at our disposal.
If you're looking for deep, in-depth articles, new projection systems, etc, you probably won't find that specifically on any forum, as they aren't something that can be mass produced. They take extensive work. You may find them discussed here though. We have had members that have produced these in the past.
General forum activity will pick up once the season starts. The board's fantasy leagues are quite active all year.
