The Giants struggled last season as they got off to a 0-6 start, but they won seven of their last 10 games to finish 7-9, although they missed the playoffs.
"In terms of Tom's future, we haven't even had that discussion yet," Mara told ESPN. "He's obviously going to be our coach here next year and hopefully for longer than that, but we haven't sat down to even talk about that yet.

The 67-year-old has won two Super Bowls with the Giants and has been at the club since the 2004 season.
