So according to https://www.drafttek.com/NFL-Trade-Value-Chart.asp?RequestTeam=cin it appears ON PAPER as though a middle of the 5th is more realistic for our three 6ths. However, to Sparky's point, there are teams that are looking to add cheap quantity (cap hell?) over quality, and the trade value chart is just a rough guide and always has glaring exceptions every year. To answer your question, no I wouldn't expect the Bengals to trade their 4th for three 6ths as I believe the Bengals are looking for quality over quantity with plenty of cap space.
