Project O = Olympique Saint Louis secondary

I tried and tried and tried and tried to create a slick secondary logo featuring a stylized "STL." Admittedly, this is a stretch, but I like how the cast iron ornament design works well for the S and the Torch-T ... and the symmetrically inverted-S-as-L.

So if you believe that, then the OSTL acronym is all here: the red roundel O and the cast iron STL.
