Am I a bad seahawks fan for not knowing this existed?
"The Miami Seahawks were a professional American football team based in Miami, Florida. They played in the All-America Football Conference for one season, 1946, before folding. They are notable as the first major league sports franchise in Miami and the state of Florida's first professional football team."
They had one Season and went 3-11.
Interestingly, I used that "what if sports" thing to pit the 1946 Miami Seahawks vs The 2012 Seattle Seahawks (at Miami) against each other.
We won 43-0.
