ARLINGTON - CHANNEL 5's coverage of the Dallas Cowboys, which began at training camp in California in late July, ended prematurely on Sunday when Green Bay kicked a field goal on the final play of the game to upend the NFC's top-seeded playoff team 34-31.  Sports Director Joel Villanueva was in Arlington for the playoff contest, just as he was in Oxnard when the season began.  He files a closing report on the team's final effort of the season.
