The Lions apparently have decided on their new logo. It has appeared on NFLShop.com on a toy collectible truck.
There is a picture available here: http://www.lions-blog.com/2009/03/the-new-detroit-lions-logo/
In my opinion it is hard to call that a new logo. They added a few white line and a tooth? I guess time will tell if there will be a color change to the uniforms to go with the “new” logo.
