For the fourth consecutive season, the Steelers will bring back the same exact starting offensive line in 2018, something unheard of in today's NFL.
But it's unheard of because of free agency. Teams just don't often invest as much money in their line as the Steelers have in their current group of tackles Alejandro Villanueva and Marcus Gilbert, guards Ramon Foster and David DeCastro and center Maurkice Pouncey. The depth also has been impressive, as well, with Chris Hubbard and B.J. Finney starting key games in recent years.
That depth took a big hit this offseason when Hubbard, who made 10 starts last season, mostly in place of Gilbert at right tackle, signed a five-year, $36.5 million contract with Cleveland in March as a free agent. The Steelers couldn't come anywhere close to that deal and will face tough decisions at the end of the 2018 season with Foster and Finney, who both will be free agents.
