not so good (compared to cf.net), but: www.houstonprofootball.com there is NO bbs like this -- anywhere, for anything! word.
The official houstontexans.com website has a BBS, it's probably the busiest since it's the official BBS for the Houston Texans. There is a 3rd BBS for the Texans other then the 2 mentioned here, but can't remember it.
