Trout's "True Average" would be lower if he were on a better team. His OBP goes up 50 points when runners are on base. Pitchers don't want to give him anything to hit when he can hurt them, and they're right to do so. Mookie's scored 40% of the time he's reached base and Trout only scores 26%. If Trout had Benintendi, Martinez, and Bogaerts hitting behind him, his overall OBP would come down some.
