Grullon is starting to look like he's for real (especially hitting HRs on the road, I don't take home stats seriously at Reading anymore, they really need to fix that stadium). I'll withhold judgment until he has a full season (really, half a season on the road) and his numbers stay strong.
It doesn't mean you don't take Bart, if he's BPA, take him and bring him along.
Even if he starts at Lakewood, he'll be in Clearwater next year while Grullon is in Lehigh
You need two ML catchers, Knapp is a ???, and Alfaro is so athletic that if a young catcher were to be the "real thing," Alfaro could split time there and play other positions if his hitting continues to improve (with his quickness, agility and arm, he could be a potential Gold Glove at 3B if he has soft enough hands).
I'd prefer Bohm, but it comes down to scouting. A similar bat is more valuable at C, even as trade bait.
Worst comes to worst, both Grullon and Bart pan out and you trade one in two years for a position of need.
