"The New England Patriots' quest for an undefeated season is as big a bonanza for the National Football League as for the team's fans.

While building a 14-0 record, the Patriots have attracted the largest audience in cable television history and the most viewers ever for a Sunday night NFL game. The team also generated the biggest TV audience for a Sunday afternoon game in at least two decades for the most-watched U.S. sports league. Sales of team merchandise are up, too.

``They are just a steam engine going down the tracks,'' said CBS Sports President Sean McManus, whose network is televising this weekend's New England game against the 1-13 Miami Dolphins in Foxborough, Massachusetts. ``The Patriots have been a great story for us. They're the driving force behind our ratings.''"
