Tough question. Definitely keep Young. The tossup is between MCab and Teix--MCab's AVG and HR should be great, but his RBIs will suffer with this year's lineup. Teix should be just as good as last year. MCab is younger and a better overall hitter, so his HRs could increase AND he plays 3B. Me, i'd go Young/Mcab, as you should be able to draft a better 1B than 3B from what's left after keepers.
Viva la Revolucion!
