If Renfroe is a prominent non-tender candidate, they aren't getting much in talent back for him. A direct quote from your first response to me: "It's not like you'd non-tender them."
Lauer IS a back of the rotation, innings eater. Nothing more. He's not bringing back a "valuable high leverage reliever" (again, quoting you). And even if he did, that reliever's salary would be as much, if not more than Lauer's.
They WOULD have to get rid of a bunch of salary to sign Abreu. You are probably the only one on the planet that thinks, "hey, they'll just add $20 M to the payroll to sign Abreu." I picked Renfroe, Tellez and Lauer/Houser because their combined salaries are about $20 M Abreu will get. It could be Renfroe and Adames. That's about $20 M, also.
