1. Walker is past his prime. Let's not have another Weeks, Hart, Ramirez, Marcum, Wolf, Lohse, or Garza decline candidate. They had unexpected success last year precisely because they stopped making personnel decisions like that (pretty ironic that "giving up" can actually make you win more because of the benefits of youth). 2. Villar is not yet in his prime and has the equivalent of only 3 full seasons. 3. Villar's first full season was better than any of Walker's 8. He doesn't have to repeat that to be the right choice. 4. Range matters; I bet you can make roughly twice as many errors and still be more valuable on defense than a slower guy. 5. Base-running mistakes are irritating, but it's similar to range on defense; you can make up for it and then some with speed. 6. Villar could be a valuable trade asset with a bounce-back year. 7. Sogard is a better defender and a legit backup SS. 8. The money could be utilized better in other ways, either on a starter now or at the trade deadline. 9. If Villar fails, guys like Perez and maybe Dubon probably deserve a shot. Bottom line, Villar doesn't have to be 2016 Villar to be a better option than Walker. Asset management is what got you here, so just keep going with that. Villars range and speeed didn’t nearly make up for his mistakes. The metrics show that.
