The success of the Pittsburgh Steelers has been tied to their ability to be the most physical football team on game day, with all six Super Bowls being built on the back of gritty and determined players. Most of the time, this mindset is associated with the Steelers defense, but the offense has been just as resolute, especially the center position. Iron Mike Webster is the biggest example, but Dermontti Dawson, Ray Mansfield and Maurkice Pouncey have also set the tone for many great Steelers teams. Recently, the Steelers have struggled at center, but Zach Frazier could change that.
