Kubel moved through the minors just as quickly as Arcia, but with a SO% that was half that of Arcia's. Setting that aside, let's say he turns out to be pretty much Jason Kubel, maybe with a bit lower average and a bit more power, or maybe not, but pretty much the same net offensive value. Here's the problem with that. Jason Kubel wasn't very good. Like several other Twins hitters, he had a career year in 2009, putting up an impressive 135 OPS+. But other than that, he posted OPS+'s of 110, 115, 105, and 110 in his 4 other full seasons for the Twins. Throw defense into the mix with WAR and it gets even worse. 0.4, 0.6, 2.5, -0.4, and 0.7. Ouch. So unless Arcia is Kubel 2009 instead of just Kubel, he'll be a disappointment after his rapid advancement through the minors. I'm hoping for the '09 version. Either way, he'll be fun to watch.
