A lifetime of seeing Belichick know what we are doing before we do.
Actually Tedi Brischi once fessed up that they knew our playbook. There was a interception in the final game of 2003. We were losing 31-0 but at the 2 yard line, about to score to break the shutout. Bruschi said he knew exactly where we were throwing, stepped in and preserved the shut out.
Ever since, I don't trust the Pats, especially in Foxborough.
