As my season is completely in the gutter and I am likely trying to overhaul everything next season. The following players are on the trade block
DE Melvin Ingram (92 - 29yo)
HB Christian McCaffrey (90 - 27yo)
Both are expiring but young so you would be trading for them with the intent to resign them next year rather than treating them as rentals. For the cost a rental would fetch, I'd just keep them
Their OVRs may have changed during the season with how trash the team has been but I can have KCF verify if there's any interest
