I'm agree with those saying it's too early to worry about this "problem". Dozier's bat may not hold up next year, Rosario could falter, and I don't think the Twins are exactly stacked with corner outfielders. I could definitely see Rosario shifting to the outfield, for a little while at least. But since we're talking about it, I'd rather trade Dozier if the time comes. If Rosario is banging on the door next year, I'll take his higher upside and four extra years of youth. I do not think Dozier is a SS.
