A big part of the discussion came from the digression of someone thinking that a replacement-level player would cost several million dollars, and another not understanding that being available for the minimum salary is very much a part of the definition of a replacement player. It's not just their literal projections either, i.e. ZIPS. ZIPS does weird things with middle infielders. You can look at their careers and recent results and see the -X WAR performance coming pretty clearly.
