Was Washington Redskins Namesake a Native American Imposter?

For 20 years, Native Americans and others have been trying to get the NFL's Washington Redskins to change the team's name. But the owner, Dan Snyder, says it's meant to honor the team's first coach, Lone Star Dietz, who claimed to belong to the Sioux Nation. President Obama has joined the debate over the name saying, if he were the owner and it offended "a sizeable group of people, he'd change it…even if it had a storied history." Well, it does have a storied history all right, but the story itself might not be true. Richard Lieby has covered it for the Washington Post, since it first became controversial.
