Calm down. On that last series I saw a couple of basic errors that can be improved on. On the TD run Tracy White, who should never have to be on a regular defense takes on the lead blocker with the wrong shoulder essentially opening up the outside lane. He he hits with his inside shoulder and keeps his out side should free there is no hole.
This is a bad a run defense as I have ever seen by the Pats in 50 years of watching them. But from what I've seen it IS correctable Unfortunately being forced to play guys like Slater, White and Brown could mean its impossible
