Quinton Spain has signed his 1-year tender according to his agent:
We talked a lot about Spain leading up to free agency. He was a restricted free agent, and the Titans tendered him at the lowest possible level. They would have had the opportunity to match any offer Spain was given by another team and would not have received any compensation had they let him go to that team. Obviously those offers did not come.
The Titans have added Xavier Su’a-Filo and Kevin Pamphile in free agency.
