The worst record would be winning no games at all, unfortunately this tends to happen to some teams.
It depends upon the league/sport. In the NFL, for example, the team with the best overall record wins their division. In the event of a tie, the division record acts as the tiebreaker. I believe the best conference record wins the conference in NCAA Football, regardless of overall record. Then there are the league like the NHL, where a team earns 2 points for a win, 1 for a tie or post regulation loss--with the team accumulating the most points winning their division/conference.
