For his 236 innings at SS Polanco contributed 1.1 WAR in spite of below average defense. In 1360 innings Falefa contributed 2.3 WAR thanks to his glove. Polanco’s bat out trumps Falefa’s glove here in a big way.
The 2019 line up was awesome because of the contribution of Garver and Polanco at catcher and shortstop. The 2022 line up with Arraez, Garver and Polanco would have been difficult from 1 to 9. Bullpens would be taxed and thinned by the last game of the series. The 2022 line up now looks to have weak bats at 8 and 9.
I get the injury risk to Polanco playing him at SS and the injury risk to Garver. It is that the upside of healthy seasons from them that was the path to winning the central. Instead they chose the safety of mediocrity. The Rangers with Falefa as their SS for nearly every inning ranked 19th at SS last year. I would expect the same safe mediocre neighborhood this year.
