My dad stopped by and we saw that play live. I just exclaimed "OH! THAT WAS BRUTAL!" and my pops says to me right away "yup, and it was perfectly clean."
Hahahahaha of course it was...
Maybe if Pollard wasn't getting blocked into Brady's knee he would have hit him in Belicheat's preferred zone.
No non-biased viewer will say it was dirty. It was far from it. At least he didn't pull one out of the Pats' playbook and hit him in the knee with an elbow.
