This decision means that the team can continue to use the Redskins name, but it will lose a considerable portion of its ability to protect the financial interests connected to the use of the name. If others printed the name on apparel, or other team material, it will become more difficult to go after the groups who use it without permission.
The owner’s decision to continue to use the name have been increasingly criticized and widely acknowledged to be offensive. Time will tell if owner, Daniel Snyder will continue to be as adamant in not changing the name. My guess is financial barriers may motivate him at some point, if nothing else.
