Why on Earth would you get your hackles up over the minutia of how to classify the Dolphins? "Middle of the pack" is a pretty broad term. It definitely isn't cause to say someone's wearing rose-colored glasses and making false statements about the team.
People love arguing semantics. If we finish 7-9 "it's another losing season" and if we finish 8-8 "it's a non-losing season" like there's really any significant difference between the two minus the rhetoric.
