Fewell has spent the last couple of days weighing his options after he interviewed for both New York and the Chicago Bears.
He has made his decision, and Tom Coughlin announced it late Thursday afternoon.
What does this mean for the New York Giants? Well, for one thing, it means they will have a defensive coach who will demand accountability and effort from his players.
I also have a strong feeling that he will not play favorites; everyone starting job is up for grabs. Obviously, the players who are worthy will retain those starting positions, but Fewell is not laid back nor afraid to come down on players who don't bring it every play.
Fewell is best known for getting everything and more out of an young, seldom talented Buffalo Bills defense. It seemed that every year some young stud would play great and go and get a contract somewhere else.
Fewell had a lot to do with the young player's development. The most encouraging factor in his arrival is the fact that the Bills had the No. 2 pass defense in the NFL this year, something the Giants definitely need to work on.
The Bills were awful in run defense, but they faced a number of injuries to their front seven and, like the Giants, could not recover.
The speculation will most likely surface as to whether or not the Giants' front office believes Fewell is the head coach in waiting. Coughlin still has two years left on his contract, and it is extremely doubtful he will continue coaching at his age.
Fewell will bring heart, motivation, and accountability to the defense. His demeanor has always been one of passion, and will look to revive a defense that vastly underachieved and was marred by injuries.
Now that the Giants have a man in place, they can start working on implementing a system, as well finding out who will stay, and who has played their last game in the Big Apple.
The Giants are one of the youngest teams in the league, especially on defense, and the potential is endless. Hopefully they won't see as much time in the training room this year.
