Number 3 in the link above is interesting. May not be too relevant (different team, different year), but goes against the narrative of Peyton choking vs the Cheats*. I also think the key to beating NE* any time is to get them away from home (and the locker room bugs that it appears many teams believe exist, the extra helmet frequency found during Spygate, etc).
