The loss could be attributed to many factors, including that there was a lack of defense, that Tom Brady had the ball stripped from him late in the game, or that Tom Brady’s hand was injured so he didn’t catch the ball on the trick play throw to him. Regardless, he himself didn’t throw the win away.
Personally, I attribute the loss to the fact the Eagles were the hungrier, more talented team that played to win rather than playing “not to lose”. It was a riskier gameplan, but it’s the only way to have a chance to beat the Patriots.
If you wanted a quarterback that would make a fun Super Smash Bros. character, it would be Brett Favre: He’s a gunslinger who rarely gets hurt, but sometimes he just throws interceptions. No rhyme or reason. In the game of Super Smash Bros, you’d basically never have control and just watch him try to win the match for you. Great character for the “never played this before” participants.
