Performance histories are Open Leagues only, afaik. And I doubt owners tank players for the performance history -- wasting 12.95 is not worth increasing your chances to win a team that costs 12.95...
That said, put an OL team in Coors, get another handful of Coors/AFC/etc. teams in the league and watch the HRs crank up... bad seasons do happen, especially if pitchers start pitching fatigued...
