King and Hayden would be rentals. Both of them are on expiring contracts. Hayden is a bit long in the tooth and King is going to want to get his $$$. Mercilus comes with a hefty price tag, $10,000,000 to $13,000,000+ per season over the next 3 years, and he's already 30. Adkins is 32 and comes with a hefty price tag as well. For a team with only $4,000,000 in cap room I don't really see us making those moves. The Giants have been talking up Engram and I'm not sure if they will let him go. He has his 5th year option at just over $6,000,000 left out there after this season, due to be a UFA in 2022.
