The Royals had a surprisingly good year last year, and the projection systems do not expect a major regression as the team is currently constructed. Dan Szymborski of Fangraphs has his annual ZIPS projections out for the Royals, and it reflects much of what the fanbase has already determined - a superstar player surrounded by a weak crew of hitters in the outfield, a strong starting rotation with an average bullpen.
Szymborski writes that while we shouldn’t expect Bobby Witt Jr. to put up his MVP-type season every year, he is still extremely good and his projection over the next five years is better than anyone except Aaron Judge or Shohei Ohtani.
