Bill Belichick, the Patriots coach, made a questionable call during the game, and failed to act in a leader-like manner at the end of the game.
The questionable call came when the Patriots had the ball at the Giants 39 yard line. It was first down, and Belichick had to choose: try for a field goal to get three points, or try to keep the ball moving in the hopes of scoring a touchdown. He chose to go for a touchdown, but they failed.
In hindsight, getting the three points could have sent the game into overtime, and provided the Patriots with more opportunities to win the game. He made a tough call, he took a chance, it didn't work out. That's okay.
However, at the end of the game, while there was still one second to play and the Giants had the ball, Belichick chose to get off the field and returned to the locker room, while leaving some of his players on the field to complete the game. That is not the mark of a great leader.
Even if he was disappointed, even if the situation was difficult, as a leader he should have stayed on the field until the game was officially over. He came on the field with a team, he should have left the field with that entire team.
As the coach, he basically showed utter contempt for the rules of the game, and worst of all, for his players. It will be interesting to see how fans and players react to that behavior.
