I'm avoiding the massive sites this year... Seems like they are forever crashing or running at a snail's pace come gameday...
The site I'm using this year for the league's where I pay a host is
http://www.Xpertsports.com . They have the most flexibility of any pay site I've found, and the unique all-in-one layout of their league pages is awesome once you get used to it... They've got good forum capabilities for smack-talk, and their draft engine is second to none, IMO... It takes a couple minutes to get used to, but once you're used to the lay-out it's hard to beat...
