The Kansas City Chiefs have an all-world safety in Eric Berry who needs to get a new contract done before July 15th, otherwise he will play on the 10.8M Franchise Tag designation. The Chiefs tagged Berry to keep him exclusively theirs and to try and negotiate a long term deal, but that tag becomes permanent for the season if no long term deal is struck by July 15th.
Now there is a new report from Ian Rappaport that the Arizona Cardinals are "Deep in Negotiations" with their own all-world safety, Tyrann Mathieu.
