Some loyalists may dispute this belief. They will claim that two Super Bowls is enough to warrant a perennially cold seat.
The current state of the New York Giants says differently. As the football world has waited for New York to rev up the playoff engine, the Giants have instead fallen flat on their face in consecutive weeks.
First, New York suffered its first shutout since 1996 at the hands of the Atlanta Falcons. That loss should have been the motivation this team needed to feel a sense of urgency. Instead, New York laid another egg against the Baltimore Ravens in Week 16, falling 33-14.
Far too often this season New York has looked sluggish, slow and undisciplined. A team based on offensive balance and defensive efficiency has showcased nothing of the sort this season.
It is maddening how inconsistent this team has been, from Eli Manning and Justin Tuck all the way down the roster. Tuck has a mere three sacks while Manning has thrown 15 interceptions.
After winning six of their first eight games, the Giants have since lost five of their last seven. New York is a shell of its Super Bowl self from a season ago and the head coach must be held accountable.
Coughlin has almost his entire roster back from that team and yet this is a completely different football team.
Take the loss to the Ravens as the perfect example. Eli Manning failed to establish offensive consistency or presence and the defense allowed Joe Flacco to look like one of the best QBs the game has to offer as he threw for 309 yards and two touchdowns.
There is a talented unit hiding somewhere within the Giants depth chart and it is Coughlin's job to ensure the team shows up to play each and every week. There are so many questions right now and yet answers are non-existent.
The reining Super Bowl champions have been virtually knocked out of playoff contention. It is a reality that did not seem plausible before the season or even midway through it.
Fingers are going to be pointed in New York, and they should be directed at Coughlin.
