GM Jerry Reese to Giants co-owners John Mara and Steve Tisch: Fire away, fellas. Reese provided Mara and Tisch with the blueprint to fire him at the end of the season – his fifth in six years without making the playoffs with no playoff victories since Super Bowl XLVI – by claiming to take full responsibility for the Giants’ disastrous 1-6 start in what is perhaps the most disappointing season since they went into business in 1925. “This is the roster that I put together,” Reese said Tuesday. “I’m the reason we’re 1-6. But we do have to play better as a team.” Reese tried to turn himself into a martyr Tuesday ... until he didn’t.
