Coach Taylor's (Kyle Chandler) career as a fictional football coach mirrors the path "Friday Night Lights" has taken as a series.

For three years Taylor was successful but never won over the Texas community - then he got replaced and went to a smaller school, where he finally earned respect.

"Lights" was incredibly strong for three seasons, yet never gained a big audience. Then it was dumped by NBC and picked up by DirecTV before earning a couple of Emmy nominations.

"Friday Night Lights" enters its fifth and final season this fall as one of TV's best shows. Its success stems from its concentration on relationships and family. The gridiron is always present, but the show shines when it focuses on the characters' issues away from the game.
