In 2004, (I'm getting my 2004 numbers here,
http://profootballreference.com/years/tmstats2004.htm) I can't vouch for the accuracy, but I'll take their word that they're using actual data. In that Superbowl run the Pats beat the Colts (#19) You were right though, the Colts had beat the #10 ranked Broncos hadilly, but when they came up against the #2 ranked Patriots, it was too much, and their #1 ranked offensive unit was able to muster only 14 points, and they were out again. New England on the other hand went on to beat the #1 Defensive unit with 41 points, in Pittsburgh. By the way, NE was the #4 offensive unit, using your measure of choice, as you provided above. In the Superbowl, they faced the #3 Eagle Defensive Unit, and put 24 on them. So, to sum that up, not the #19 and #10 and #3 you claimed, but the #19 Colts, by also shutting down the #1 offense. Then they took the #4 offense on the road to take out the #1 and #3 defenses. Yeah, the road was alittle tough for Tom Brady and the Pats. IN fact, it couldn't get much tougher. Not to mention just to win the division, the Jets were the #4 unit, and the Bills #8. The 'Fins were all the way down at 20. Maybe facing those top notch units all year conditioned them for the playoff run?
