I'm glad there's depth, but let's not forget how many MLB position players started at SS. On the current team, at least Dozier, Sano, Polanco, Santana, probably Escobar. In the past: Cuddyer, Plouffe, Joe Nathan...SS is a position "athletic types" get in A/AA and a lot changes with time. Depth is great, but don't mistake it for ready MLB talent. I'm never a fan of trading a MLB player under the premise that there's somebody "in the pipeline" unless it's an immediate upgrade. (I'm not opposed to trading MLB talent for other reasons.)
