Apparently the officials stopped using the Patriots balls in the first half. The Patriots also put up only 17 of the their 45 point in the first half as well.

That said, I don't know why a team of the Patriots caliber need to seemingly continue to pull stuff like this. I am a Patriots fan, but I find it disappointing and very frustrating to see them doing this stuff.
