The Steelers offensive line is one of the top units in the league and has been for the last five years. That has been in large part to the coaching of Hall of Fame coach Mike Munchak.
Munchak has done wonders for the Steelers consistency and performance across the entire front five. He also played a key role into turning Alejandro Villanueva into the starting anchor he has been in Pittsburgh.
His ability to develop and coach any lineman into being at the least a serviceable starter has been exceptional in his time in Pittsburgh. His coaching helped keep the line performing at peak ability when Marcus Gilbert missed most of the last two seasons and plugged in Matt Feiler and Chris Hubbard.
Mike Munchak is now with the Denver Broncos and the Steelers had to promote Shaun Sarrett to offensive line coach. Sarrett has been here for seven years and learned under Munchak for five.
The Steelers line is a key reason Ben Roethlisberger has stuck around and they will need to continue their performance as one of the best units to keep Ben around.
Villanueva, Maurkice Pouncey, David DeCastro and Marcus Gilbert are all signed through at least 2019. Ramon Foster is due for free agency but I look for the Steelers to sign him early in free agency or possibly before it begins.
