Yes. Dolphins are usually thought of as being such tough, manly creatures. A bit like Unicorns and ponies
I read somewhere (several years back), that when the team was introduced they did a poll to vote ona team name. Sharks was a popular choice. When they decided on Dolphins, it was pointed out that Dolphins can kill sharks. I agree it doesn't sound intimidating, but it is what it is.
What do you think is the best NFL team name? I go with Giants.
