NFL Thursday: Lions, Cowboys and Steelers have upper hand NFL today TV: Channel 11, 9:30 a.m. Line: Lions by 6. Over/under: 50. Sam Farmer's pick: The Lions have lost two games in a row, and Coach Jim Schwartz's chair is getting toasty. But Detroit should be able to beat a hobbled Green Bay team that is on its fourth quarterback in Matt Flynn. Lions 28, Packers 20 TV: Channel 2, 1:30 p.m. Line: Cowboys by 91/2. Over/under: 471/2. Farmer's pick: The Cowboys are coming off a big NFC East victory over the New York Giants, and the Raiders lost another close one. Oakland should keep things close against a bad defense, but Dallas has the edge in this traditional home game. Cowboys 24, Raiders 17 TV: 5:30 p.m. PST, Channel 4. Line: Ravens by 21/2. Over/under: 401/2. Farmer's pick: If history is a guide, this game will be very close and very physical. The last four meetings were decided by a field goal. Pittsburgh's Ben Roethlisberger has collected six touchdowns and no interceptions in the last two games. Steelers 21, Ravens 20
