guaranteed winner: CAROLINA
(each team can only be used once per season, PITT, NE, MINN, INDY, STL, KC, ATL, SF, DAL, TN, NYG, HOUS, CLE, DEN used, 9-5)
guaranteed loser: SAN DIEGO
(each team can only be used once per season, OAK, STL, INDY, PHIL, NYJ, TN, CLE, BUFF, CHI, DAL, MN, TB, GB, NYG used, 10-4)

this is a rough draft of the AFC wildcard tiebreakers ... example, the JETS have the tiebreaker only over MIA, with NY-SD tiebreaker still to be determined, depending on outcome of games. [This actually assumes the tie is a result of a NY victory over MIA in week 17.]
