It's semantics, but there's a difference between "losing" a year by only getting 6.0 out of him and "using" a year by still getting a bunch of extra months, but using them up a year earlier. And they are all very recent, which leads us too... It's pretty unnecessary, and the consensus seems to be that you'd rather leave him at SS longer in that case to make sure he's getting as many ground balls as possible. For long stretches, the best way to prepare to play 2b is to play SS. We're not close to running out of bad players that could be cut with no remorse.
