There are positives and negatives to all of these guys. Plouffe's got spotty defense and he's streaky, but his overall hitting stats are nothing to complain about. Dozier needs to show more at the plate, but he's really taken to second base. It's early on these guys, and we shouldn't be making plans to replace them with A ball players next year. The only way I see Sano and/or Rosario up for a large chunk of time next year is an Arcia-type situation, where injuries open a spot and they grab it and don't let go. More likely, they won't be ready regardless of whether they get a short look on the 25-man, and the whole thing is probably a moot point for 2013/14. Honestly, I think any average-ish major leaguer (or worse) should be constantly worried about their roster spot. But the ultimate hope is that Dozier, Plouffe, et. al. work out the kinks from their inexperience at the major league level, find some consistency, and become good everyday players. By late-2014/2015, if Sano and Rosario are as advertised, then we should take whatever Dozier/Plouffe/etc. get us in trade or be happy that we have competent backups. But we can't make any kind of solid plans for 2015 today when the guys being talked about as replacements haven't even hit AA.
