It's Tuesday, so what better night to premiere a show called "Friday Night Lights"? Yeah, we think it's a pretty boneheaded move on NBC's part, but the networks seem terrified to schedule anything of real quality on Friday nights because they think people don't watch TV on Friday nights. Have they ever considered the notion that people don't watch as much TV on Friday nights because there isn't anything GOOD ON? "The Ghost Whisperer"?......
