In 2013, Anthony Spencer and Demarcus Ware got hurt. That was also the year the Ratliff decided to not honor his contract.
In 2011, Flozell Adams, Leonard Davis, and Andre Gurode didn't make it out of TC making what was going to be a transition into a rebuild
Both were issues with pro scouting. You cannot fix those problems in July no matter how much Sturm might insist.
Sturm is playing sophist with this one. There have been no doomsday cap years since the late 90s and we currently have $10m in cap space with more coming down the pipe. We are going to have no issue signing Martin and still have room to add more FA. We have more cap room coming down the pipe.
