I think 99% of the ripping is schadenfreude from other teams fans. I have no clue what anyone means when they say the Chargers logo looks like the Rams, they are vastly different aside from a minor color scheme variation.
Now if you want to rip on other logos i think patchy the raider is pretty ridiculous and the Norseman Viking is just silly, don't even get me started on the flaming blue cat an..s of the Titans.

Get the uniforms right and all is forgiven, and if you can't get that right win some Super Bowls and we'll all learn to love those uniforms every time we see Super Bowl highlights for years to come.
