Well, now we know why the Cowboys have been so interested in trying to extend the contract of quarterback*Tony Romo.Apart from the importance of reducing his $16.8 million cap number for 2013, Romos contract was crafted in a way that prevents the Cowboys from applying the franchise tag in 2014.According to Ian Rapoport of NFL Network, Romos contract*extends beyond 2013 by three years.* (According to NFLPA records, it definitely does.)* Thus, Romo will become a free agent in 2014 not by the expiration of the deal, but by the voiding of the final three years.And while the deal apparently doesnt include a no-tag provision, Rapoport explains that the deal will void after the deadline passes for using the franchise tag.In other words, Romo wont be a pending free agent and in turn not eligible to be tagged during the two-week franchise-tag window in February 2014.* Then, after the window closes, the contract will void, making Romo a free agent.Allowing that loophole to exist in the deal would be enough to get the owner to fire the General Manager.* If the owner wasnt the General Manager
