According to the Press-Gazette, FB John Kuhn received a restricted free agent tender contract offer for 2011. But since it was the lowest tender of $1.226 million, the Green Bay Packers wouldn't receive a draft choice if he signs elsewhere. And it's unlikely he'll be a restricted free agent anyway because he has a five years of service. It's expected players will become unrestricted free agents after four or five years of service.
With a solid roster of tight ends and full backs already on the roster, and the return of RB Ryan Grant eliminating the need to use him as a running back, they could afford to let him go. But he's a solid contributor on special teams and I expect they have a mutual interest in his return to Green Bay. If nothing else, the contract tendered lets Kuhn and his agent know exactly how much the Packers are interested in paying him. Add a couple more years to that contract, plus a little guaranteed money, and that's probably a contract offer that could work.
