The Pittsburgh Steelers haven’t determined yet whether to retain Russell Wilson or Justin Fields—depending on whom you ask. Some seem much more sure than others that they already know. Those tend to be members of the national media, while local reporters are sure those discussions haven’t yet happened.
Of course it takes two to tango, and Wilson and Fields can decide when the Steelers make a decision. Both are pending unrestricted free agents, and both have the right to test the market. As much as the Steelers may want to do a deal before then, the only way they can prevent that is with a tag.
