A smart team might be able to parlay Yankee interest in Castillo into creating some payroll space AND deepening the farm system while also still competing for a division title.
Reds trade Suarez (sigh), Castellanos, Castillo, and Barnhart for Garcia, Schmidt, Dominguez, Torres, Sanchez, Andujar, and Frazier.
Reds then, with the around $20M in this deal added to reallocation funds from earlier penny pinching, sign Paxton to a incentive-laden deal to replace Castillo plus a closer from among Brad Hand, Alex Colome, or Kirby Yates to boost the pen. They'd probably still have money left over for either another gamble on a pitcher or assorted depth.
