"Good teams win. Great teams cover!" It's a phrase CBS Sports personality Nick Kostos utters often. When it comes to Monday Night Football, Kostos lives it. Kostos backed the Chargers plus 3.5 points last Monday night; when L.A. covered in a 24-21 loss, it made Kostos an incredible 17-8 picking MNF games since SportsLine launched. Now, Kostos -- a lifelong Giants fan who knows the team better than almost anyone but doesn't let his heart affect his picks -- has unloaded on Monday's matchup. Is he backing his beloved G-Men minus a field goal? Or was he impressed by the Lions scoring 35 points in a Week 1 thrashing of Arizona? The man who's made his name picking MNF just locked in his pick... Join SportsLine now to see what big x-factor determines which side you need to be all over in Giants-Lions, and which team shocks the NFL on national television, all from the expert who has dominated on "Monday Night Football".
