It's fair to say that the Cincinnati Bengals didn't do a good enough job of protecting Joe Burrow at the beginning of his career. Some of that is due to the fact that he was, after all, drafted first overall to the NFL's reigning worst team. Not going to be a roster cupboard full of elite players as is.
But ever since Burrow went down with an awful knee injury as a rookie, and the offensive line was exposed throughout their playoff run to Super Bowl LVI, the Bengals have been far more proactive about fortifying the trenches in front of their franchise quarterback.
