The reason they got caught was they were turned in by the head coach of a team they were playing. Said head coach being the Pat's defensive coordinator two years prior.
And I wasn't "excusing" it. I was attempting to explain why Billy is so incensed over the reaction to it. For the media and fans of other teams to be jumping up and down is one thing, but for other coaches.............?
You want a better analogy? How about: Younger brother takes cookie from cookie jar 10 minutes before dinner. Older brother takes cookie from cookie jar 1 minute later and younger one yells: "MOM!!! Billy's taking a cooooookie!!!!"
