It isn't conference record, it is common opponet record. It all kinda sucks.
Denver doesn't need to win
If SD wins they still don't get in because of worse common op sched than pit
If SD wins they put out KC because of com op sched even though SD can't
make the playoffs
KC has a better common op sched than Pitt so they can get by pit but not SD
Bottom line SD only plays as spoiler to KC
Pit is in with SD win
KC is in with SD and PITT loss
SD is out no matter what
Denver doesn't give a shit
Here is more playoff crap: Jacksonville win will give them 12-4 record, Possibly only Seatle and Indy will have more wins in the NFL and still they won't get a home game or a bye throughout.
