The soap opera starring the Minnesota Vikings and Percy Harvin has yet to reach its climax. It's getting there, though. Harvin is entering the final year of his rookie deal, and there remains a great element of the unknown in regard to his future. There's no denying Harvin, 24, and Adrian Peterson can form the nucleus of an explosive offense, but keeping Harvin healthy and content has been another situation entirely. Vikings general manager Rick Spielman, speaking Friday with KFXN-FM in Minneapolis, isn't about to show his hand at this early stage.
