Mr. Harwood, the attorney, says he contacted the NFL in 2005 about the tape. He says the league sent him a letter on Dec. 16, 2005 claiming the NFL was the exclusive owner of the copyright.
I have to wonder if that can be true. With no recording known to be made at the time, would the NFL have bothered to copyright it? It doesn't seem likely that their current copyright could be made to be retroactive.
