The MLS continues to grow in both size and popularity every year. The Philadelphia Union will begin play in the spring of 2010. This week the team officially revealed its soccer uniform colors, and the logo and crest that will adorn these new soccer uniforms. The team will be playing in navy blue and gold, and the logo features a rather menacing looking snake. But does it mean anything. Philly being as proud of its history as it is, of course the newest sports side in town would design their soccer uniforms to reflect that.
