When it comes down to it, the Chargers didn't have what it takes to be champions. Agreed that NE had good breaks gifted to them by their opponents but the breaks were down to two factors: the image and presence generated by the NE team and the fact that SD couldn't handle the pressure.
Every game has gifts from the losers: simple unforced errors due to nervousness and tension. The Pats accepted the gifts from the Chargers and walked away as winners.
