As much as I love him, the confidence level on any Kepler projection is going to be WAY lower than Lucroy's next two years, even given the question marks introduced in Lucroy's 2015 season. Demonstrated MLB performance is a pretty big deal, especially at a position of scarcity (note the Brewers already have two starting MLB corner OF controlled until 2020 or so, plus two more near-ready corner OF prospects, and zero capable catchers beyond Lucroy) It's pretty clear that the Brewers would almost certainly turn down a straight-up Lucroy-for-Kepler swap, given the public information that we have. That should give you an indication of what the deal would be like for the Twins. A marginally higher prospect ranking is almost meaningless in these discussions. A Polanco for Lucroy swap would have the same issues as the Kepler for Lucroy one, meaning the Brewers still say no. Package the two together, or one of them with other players, and you're on the right track. Sanchez is an interesting target, but there are doubts about him sticking at the position, and the Twins seem particularly sensitive about that. So you might not be solving anything, and in fact just burning a trade chip to add another name to the 1B/DH logjam. And if there's any consensus he will stick at catcher, the Yankees gain a ton of leverage -- they don't really need Polanco, with Gregorius and Refsnyder slated to start in their middle infield, while the Twins and a bunch of other teams would LOVE a capable young catcher. Prospect-for-prospect trades also seem somewhat rare, which might raise the bar for the offering team (in this case, the Twins).
