All your metrics are good projections and all, but the fact is, we have no idea how he adapts. Yes, his strikeouts are a tad high and yes, speed tends to neutralize at the ML level, but guys outperform their MLEs all the time. All. The. Time.
The dude is hitting.340/.420 (I don't give a rats ass about power in a run scorer, though i think he'll develop some) and appears to have mastered every challenge. I'm willing to watch him try before deciding his K rate will go up and walk rate down and BABIP down and contact down making him Ryan Langerhans.
