There are two separate levels of offensive line evaluation, both equally relevant. You judge the offensive line collectively, how they work as a group and perform. The Pittsburgh Steelers offensive line, generally speaking, passed this test in the season opener.
You also look at linemen individually to see how they are performing within the game. Some linemen fared better than others. Center Cody Wallace, filling in for Maurkice Pouncey, was certainly the Steelers’ worst lineman on the night, though that should be expected from the one that is not a starter.
Wallace is a high-energy player who will not take a play off and give you everything he has.
