Agree across the board with the players you named above.
Still think there's a good chance San Francisco re-signs Chase Young.
Glad you mentioned Jonathan Greenard. Don't think he has gotten enough play on this Forum. Unfortunately, Houston will have plenty of off-season cap space, so we may just be wish-fully-thinking.
Can not imagine Jacksonville or Carolina simply allowing Allen or Burns to hit free agency. If they are tagged, perhaps a sign and trade could be worked-out but it would cost the acquiring team quality draft capital. The Jags and Panthers appear to be in decent (but not great) cap shape, so I wouldn't entirely rule out that those players could be available ... just Not as unrestricted free agents.
In addition to Greenard (who I would prefer), I have mentioned Buffalo's A.J. Epenesa in the past. His sacks, pressures and quarterback hit numbers are good when you consider that he only plays about 40% of the Bills' defensive snaps. Also, unlike some of the teams mentioned above, Buffalo is Not in good cap shape for 2024. Being able to retain a played like Epenesa seems unlikely.
