The SB Nation has added a Miami Dolphins blog.
Last I checked it wasn't in the SB Nation blogroll yet, but it soon will be. So check it out if you are a fan of the Dolphins. The site will have all your Dolphin needs.
Given the way sports work in South Florida, the Phinsider will be bigger, in terms of traffic, by the end the of the week than FishStripes. Such is the nature of the beast.
But be sure to go by and give it a look.
