For the second year in a row, Yoan Moncada is in that No. 1 slot. And why not? His impressive tools haven't changed just because he was sent from the Red Sox to the White Sox in the blockbuster Chris Sale deal. Beyond the stability at the top, however, is a lot of change. Only two second basemen -- Ian Happ of the Cubs and the Phllies' Scott Kingery -- are holdovers from a year ago. There were three graduations to the big leagues and four dropped off because of performance and/or others passing them on this hypothetical depth chart.
