Duke Tobin says the Cincinnati Bengals are looking to upgrade their offensive line via free agency.

"If you do spend the big money, it better be worth it," Tobin said. "It better be worth it. That better be reflective of what he is going to give you. Trey Hendrickson. If you are going to pay him that much, make sure he is worth it or at least he has the ability to be worth it. He was."

The Bengals signed Hendrickson to a four-year, $60 million deal last offseason to boost their pass rush.
