Actually, no, I don't. Lately, I haven't been in any fantasy leagues with random strangers. I've had too much bad luck with them. Between people "quitting" mid season, and just being overall morons (drafting Adam Vinatieri in the second round), I gave that up and would rather form my own league (a la last year's baseball league).
This is the exact reason that I was so excited about being invited into the ESPN Top 50 group... I knew that it would be top level gamers going all out in every league, and what price can ya put on great competition? It's also another reason I scan games histories of other drafters prior to a random league draft starting. If I see there are more than a couple of inactive profiles, I jump out of the room and go look for some better competition in the next draft room.
It's also why I value my long-running leagues like YJFF...I dig the competition.
