Polling non Dolphins fans don't count though, and I doubt that many would think it that silly. The helmet fits fine. This is football, and it's a football helmet. It's how they found a way to use the M, without making the M look out of place.
Tradition is a GREAT GREAT thing. Certainly in this case, just because you hate a helmet, does not make it a positive, or at all necessary that it be changed. Not everyone agrees with you, I'm sure of that. There is absolutely nothing wrong with someone such as myself defending tradition. It won't affect world problems whatsoever.
Like I noted to you, the Logo has only been changed once. That's it. It took 30 years for that to happen, and changing it again within 10 years in crazy. Especially when it still fits.
The teams who have changed logos the most have been around since football began. Miami hasn't been around half that long.
