It's not breaking news at all that the Bucs' decided not to use their franchise tag on Doug Martin. What will be surprising news is if Martin, in turn, ends up leaving the franchise as soon as next week.
As we inch closer and closer to free agency beginning next Wednesday, the likelihood of Martin playing elsewhere in 2016 and beyond becomes much more likely. As a matter of fact, the key day may be on Monday, once the legal tampering time begins 48 hours before players can officially sign with other teams. If Martin gets to that point without a new contract from the Bucs, my assumption would be that he's as good as gone.
