The Cincinnati Bengals are a very conservative franchise and have been that way for a very long time. Someone extremely familiar with the way they do business is former Bengal Andrew Whitworth.
After moving on from the Bengals to the Los Angeles Rams, he saw them make several big, aggressive moves that eventually helped push them to the Super Bowl. He references those moves in the video below on Twitter, where he talks about the Bengals needing to make some aggressive moves like the Rams did in order to win it all.
