Probably Head-to-Head record since you had fewer overall points than at least one of those teams. See below:

In the event that two or more teams have identical won-loss records at the conclusion of the Fantasy Football regular season, and have played the same number of head-to-head games between them, the following tiebreaking system is employed:
1 - Overall record *
2 - Head-to-head record **
3 - Overall points
4 - Head-to-head points
5 - Division record
6 - Overall points-against
* Note that Overall record is based on winning percentage. Therefore, a team that is 8-5-0 and a team that is 7-4-2 have the same winning percentage, and thus would be considered tied for overall record.
** Note that head-to-head record is based on the number of weeks won or lost during the season. If Team A defeated Team B 88-60 and then lost to Team B 92-91, their head-to-head record would be 1-1. The number of points scored in these games would be taken into consideration only if tiebreaker No.4 -- head-to-head points -- is necessary.
In the event that three or more teams have identical won-loss records at the conclusion of the season and have played a different number of head-to-head games between them, head-to-head records are not used as a tiebreaker. Instead, the following tiebreaking system is employed:
1 - Overall record
2 - Overall points
3 - Division record
4 - Overall points-against
