I'll keep banging the drum here: of the options presented, Outlaws is far and away the best. Mammoths would be fine, Mammoth sucks (I have serious qualms about singular names for a collective entity, because it gets really awkward talking about an individual from the collective. Same problem exists with the Avalanche, Kraken, Wild, etc.)
Of the options that weren't, Utah Raptors would have been so, so much better.
