Right now the Pats hold the Strength of Victory tiebreaker. The Pats are 65-85, the Bengals 61-89. If the entire AFC North wins this weekend, and the Pats beat the Texans, the standings would look like this: Cincinnati 75-97, New England 74-96. Since Chicago is playing Detroit, and Atlanta is playing TB, both teams will go 1-1 in those game. Cincinnati 76-98, NE 75-97.
That means these following games could decide the 3rd seed (should the AFC North and NE win).
Green Bay @ Arizona
Kansas City @ Denver
Indy @ Buffalo (counts 2x)
Tennessee @ Seattle
New Orleans @ Carolina
If in those games, 4 of them go the Bengals way (bold teams), they will win the SoV tiebreaker over NE and will capture the 3rd seed.
*Strength of Victory is the 4th tiebreaker, Strength of Schedule is the 5th.
