SUMMARY: The agent for T Brad Hopkins has said it appears his client won't be a part of the Titans after a 13-year career. But other members of the offensive line may also be in doubt. G Zach Piller's status is the most uncertain. He is scheduled to earn a base salary of $2.5 million in '06 and has a $250,000 roster bonus. G Benji Olson is currently scheduled to earn $3 million in '06 but there have been some talk in lowering that number and bringing him back. C Justin Hartwig is scheduled to become an unrestricted free agent on March 3 and it doesn't appear the Titans are close to signing him. What do you think about this article? Post your comments below.
