It's a four-year, $76.4 million contract extension that includes $40 million in guaranteed money. This will quickly end any speculation regarding Kittle retiring any time soon. Now 32, he's capable of being the overall TE1 in any given season and the 49ers clearly see he has a lot left in the tank based solely on the guaranteed money alone. He'll remain a premier weekly option in dynasty leagues and perfect target for a competing dynasty team one piece away from a title.
