Ben Affleck is a big Pats fan.

Jennifer Garner appeared on The Tonight Show and she shared exactly how much of a fan Affleck is. It seems that when those final moments of the Big Game happened, Affleck showed his "pure joy" that he just couldn't contain. That "pure joy" moment apparently led to Affleck being very emotional and being intensely happy about it, so much that he cried tears of joy for his beloved Patriots winning.
