Baltimore got worse. Andrew Miller fwiw walked, Markakis (warts and all, he started) left and even if you did not think Nelson Cruz would repeat his 2014, they still did not replace that pop. Showalter is a master with platoons, and he'll have to be.
Tampa got worse, although they are always dependent on the children - but the crop of kids looks less promising now than say the 2008-9 classes.
Yankees, Sox and Jays got better, but how much is questionable. The Yankees for instance got better but it might not result in actual wins (considering the last two years they had the fundamentals of a below .500 team).
