I'd give up a lot.
7 years remaining on his contract, which runs from his age 25 to 31 seasons. As a true talent 4 win player who shouldn't even start declining until the last couple of years of the deal, Freeman could be "worth" upwards of $200M dollars while getting paid about $130M.
They could have Sanchez + Hoffman to start. Probably also a couple of guys like Nay, Osuna, or Castro.
