One way to look at this - the money saved on MAT and Barraclough pays for half of Hellickson's salary.
I think the Lerners do not put money into operations of the team. Cash flow covers the operations. I'm not sure they pull money out of the team in terms of cash, and they may kick money into capital assets (stuff like the DR baseball academy and improvements to grounds at West Palm, I don't know), but I'm sure they give Rizzo full backing to fight on the nickel and dimey expenses. They did that with the city on the ballpark, which is why you have above-ground garages rather than below ground garages and usable street-scape.
