The Tampa Bay Buccaneers are working to re-sign Doug Martin, but most indications are that he'll at least hit free agency before they're able to do so. That gives the Bucs one other option: they could use the franchise tag to keep Doug Martin in Tampa for a single season.
That's not about to happen, though. The Bucs appear not to be willing to pay Martin more than around $6-7 million per year, and a single year of the franchise tag would cost $11.8 million, according to the latest projections by ESPN's Kevin Seifert.
There's an argument to be made that this doesn't matter: Martin is aging, and one year at a premium may be a safer investment than giving him a five-year contract with 2-3 years of guaranteed money. But the Bucs aren't going to do that: the Dougernaut's going to walk if they can't come to a long-term agreement instead.
