The Giants’ fortunes have pretty much been feast or famine for the last decade.

It’s been more famine than feast lately, and in a conversation Giants co-owner Steve Tisch had with the New York Post Wednesday, coach Tom Coughlin and general manager Jerry Reese could be on the chopping block if the Giants (5-6) miss the playoffs for a fourth straight year.

Tisch wouldn’t say that their jobs would be safe.

Since 2005, the Giants have won two Super Bowls, lost their first playoff game three times and missed the playoffs five times. Their championship season in 2011 was their only postseason appearance since 2008.

This year, the Giants really don’t have a running back and their defense is last in the NFL in overall yards allowed and passing yards allowed. That speaks to the lack of talent on the team that Reese has built.

The NFC East is very winnable, however. The Redskins (5-6) currently lead the Giants by virtue of a better division record. This could turn into a two-team race. The Cowboys are without Tony Romo for the rest of the season and the Eagles are reeling.

Coughlin’s job probably will be less secure if the Giants lose their quadrennial game against the Jets Sunday. The Giants have won five straight over the Jets and haven’t lost to them since 1993.

The Giants then go to Miami, host unbeaten Carolina and go to Minnesota in Week 16. That’s a tough stretch, but if the Giants are still in a position to win the division and blow it by losing at home to the Eagles in the season finale, that could mean the end for Coughlin and Reese.
