Since the merger in 1970 #1 seeds team have met 9 times.
Most of these games are blow outs with the NFC demolishing the AFC.
One would think that having the 2 best teams in football the games would be close and very competitive. The fact is one team has always been so dominant that the final scores between all 9 games average a 20 point margin of victory. The smallest margin of victory was 5 points. I realize this is a ultra small sample size and has nothing to do with this years matchup. It is bizarre though, that you get what people deem the best matchup and one team takes the other out to the woodshed. The other thing I find strange is how the NFC has a stranglehold on these matchups going 7-2 SU and oddly enough the Raiders are the only AFC team to win as a #1 seed, which they did twice.
Now again the sample size is too small to gather anything. The Niners and Cowboys make up 5 of the NFC's wins and Broncos and Bills make up 4 of the AFC's losses.
Here are the 9 games with the margin of victory in parentheses.
SB #11 Raiders 32 Vikings 14 (18)
SB #12 Cowboys 27 Broncos 10 (17)
SB #16 49rs 26 Bengals 21 (5)
SB #18 Radiesr 38 Redskins 9 (29)
SB #19 49rs 38 Dolphins 16 (22)
SB #24 49rs 55 Broncos 10 (45)
SB #26 Redskins 37 Bills 24 (13)
SB #28 Cowboys 30 Bills 13 (17)
SB #44 Saints 31 Colts 17 (13)
So there you have it. The Bengals kept it to 5 points and then the margins were 13 or more.
Just food for thought.
