The NFL has gone out of its way to protect quarterbacks, but much like a sub-par offensive line, the protection doesn't always hold up.
It's a big reason why half of the league's 32 teams -- including the Steelers -- have been forced to use a different starting quarterback this season, as Ben Roethlisberger, the Chiefs' Patrick Mahomes, Saints' Drew Brees and other star quarterbacks have all missed time.
Quarterback protection -- or lack thereof -- has been a big issue in the league this season and will be a factor when the Steelers (4-4) host the Rams (5-3) Sunday at Heinz Field.
