I don't understand your use of the term "corral." But you cannot turn off League Totals in the
OOTP results engine. They are used to define "League Average" in the Log5 equation, hence are an active part of the result of any single pitcher/hitter matchup.
League totals do not provide any cap or target for the actual number of any particular event in any particular league. This makes complete sense because otherwise you could not use the same League Totals on a league with 8 teams and one with 30 teams.
