Glad to see you're still prowling through the minors stat lines!
I was an early adopter of both Chris Taylor and Tyler Smith, and still like them both. They can't keep stacking all these guys up in the minors, but also not sure how much actual trade appeal they'd have. Sardinias was traded twice in 2015, and didn't exactly seem to have tons of market value.
Drew Jackson may be the guy most attractive to other teams, given his splashy debut and no time for the shine to wear off? It's not that unusual for a college guy from a major conference to shine in short-season and not exactly carry it forward ... Mike Zunino comes to mind. Then again, if he's "for real" you don't want to be the guy who gave him up for a bullpen arm before he even got to A ball. More like the guy you give up at the deadline if you're in contention than in the spring.
