I don't think it really even requires an explanation. The Wild logo just has so much to offer in such a small space. The Sharks logo has a broken hockey stick on which the tape doesn't even go around the stick.
You can make the case that Sharks live in the Wild. But its still dangerous for them.
I've talked before about how much the Wild logo manages to work in. The Sharks logo is all right but its not as fierce as it could be. And there's an awful lot of black used. It's a decent enough logo but perhaps it can get this point against another team.
