The 2007 Giants won almost in spite of Generalissimo Coughlin and their dislike for him.
That is absolutely ridiculous. You don't beat the...
13-3 Cowboys (#1 Seed)
13-3 Packers (#2 Seed)
16-0 Patriots (Greatest team of all-time)
...without fantastic coaching. All three of those teams were vastly superior to the Giants and had more talent yet they beat them all. When a team with LESS talent beats three teams with superior talent, it's the coaching.
A team winning "in spite" of the coach happens when a talented team wins despite having a bad coach, eg: Chargers, Cowboys. A coach deserves all the credit in the world when he leads an inferior team to victory, especially in the fashion he did.
His 2007 run was the most impressive post-season run of all-time, period. Why? Because he topped it off with out coaching and defeating Bill Belichick in the biggest game of his career. It kills me, but he deserves his credit.
Guy also had the Jaguars in the AFC Championship game,
one year after expansion, included with his 4 straight playoff seasons with them.
Coughlin is easily a better coach than "sexy names" such as Jeff Fisher and John Gruden.
All that being said though, Giants need a change as this is a collapse. Just like the Broncos and Bucs needed to get rid of Gruden and Shanny when they collapsed.
