Halfway through the first quarter in Week 3 against the Los Angeles Chargers, Mason McCormick made his regular-season debut on offense. It wasn’t at his natural position at guard, but rather as a tackle-eligible tight end, serving as a sixth offensive lineman. By the end of the second quarter, McCormick rotated in for Spencer Anderson and they switched off with each other at left guard the rest of the game.
Pittsburgh Steelers coach Mike Tomlin provided some clarity on that rotation during his Tuesday press conference ahead of Week 4. Many wondered if that was an in-game reaction to potentially poor play by Anderson, or if it was part of the plan.
