non profit logos

Is it legal to use the logos of professional sports for their nonprofit organization or team?
I just saw some sites that equipment using the logo of the Minnesota Wild and / or Jersey. I wonder if it is legal for any team or organization to use. Http: / / www.kingwild.com/ <- logo home page! Http: / / leag1.com /? Vawildhockey.com = org <- Look at all those shirts!
I think that is my legal team has used the logo Raiders

A good logo can make a website, not to be confusing and messy but clear and easy to understand. But sometimes its nice to see the odd weird logo out there,
