They probably don't want Turner in CF long-term before he has had a chance at SS. Remember Danny Santana? No team knows where it is going to be in 5 years, but that doesn't mean 5 years of control has no value. They have more options with Eaton -- if the team fades after a couple years, they can always flip him to rebuild/reload. If he struggles, well, the last 2 of those 5 years are team options. There is zero time to realistically flip Dozier, and zero chance of extending him as cheaply as Eaton is controlled. Finally, you keep assuming that Dozier is definitively better than Eaton based entirely off of 2016. Eaton has the higher career OPS, for Pete Redfern's sake. Eaton has steadily averaged 16 Rbat the last 3 years. Dozier did post 30 last year, but was actually -2 the year before that, and 13 the year before that. There is a good chance that that Dozier is no better offensively than Eaton in 2017, and an excellent chance that any Dozier advantage is relatively minor (under 10 runs or 1 win). And in terms of defensive value, there really isn't that much difference between an averageish defensive second baseman and a slightly below average defensive CF or an excellent defensive corner outfielder. The 2B positional adjustment is +4, and Dozier has averaged +1 Rfield, for a net +5 runs per season. CF positional adjustment is +3, and Eaton has averaged -2 runs in CF, for a net +1. 4 runs difference, less than half a win. Plus there is evidence that Eaton could be a superlative corner OF -- RF comes with a -6 run positional adjustment, but Eaton had 22 Rdrs in his time in RF last year, more than making up for that and even some potential offensive difference. Not to say that Dozier can't be a better player/fit for some teams, but it is not definitive at all.
