A700 said "would Marrero be a drop off from the 2014 blackhole?"
I responded "I at least want a guy with upside." Xander has shown that he can hit at times. Marrero hasn't shown that. Xander has the ability to improve on last year's numbers. Marrero does not. His glove is better, but he has a barely adequate AAA bat.
Without a decent replacement at SS, they shouldn't move Xander. If they can get someone in a deal for Craig, then they could try to swing a XB Hammels deal.
