I've always felt, and stated, that position by position a team can be built in many ways. A classic example was the Twins with Puckett in CF. At that time, there were very few CF who had that type of power and offensive ability. Most were leadoff types and defense first players. But having someone with that kind of production in CF, (or SS in the case of other teams), meant you could have a "lesser" offensive player at another position. So Mauer at 1B, playing great defense, and doing what he does offensively, is not necessarily a black hole. All of that being said, Mauer back for 2019 is a long way from being determined. Now, he has rebounded some offensively this season. Can he maintain that for the rest of the season and in to and through 2018? Another year older and with a young family, will he simply decide it's time to walk away and spend more time with them? I'm not a betting man, but if I were, if lay money he retires after 2018 to be with his family and no longer deal with the seasonal grind and injuries.
