Yes, the team that has Khalil Mack may want to add at the position where they have Khalil Mack. The fact is that they cannot rely on Mack, and need depth behind him and Leonard Floyd.
Speaking of Floyd, it will be interesting to see how they handle his fifth-year option and how he progresses in year four. You have to like what you have in Floyd, but also wonder what you pay. Floyd can do work in coverage and in contain, but may not be a one-on-one sack producer.
On top of that, they have limited depth on the roster. Isaiah Irving and Kylie Fitts are options, but Aaron Lynch is a free agent, and he carried the depth. Whether it is a name to compete with Fitts and Irving or supplant Lynch to spell Floyd, they will want to hit this position.
