So I guess you don’t count the additions of Yonder Alonso, James McCann, and Ivan Nova fornthe White Sox?
They may not be adding the bigger names you like, but they have been active, which goes for a few teams on that list.
San Diego is somewhat hamstrung in their ability to trade for bigger names, since most teams won’t look past Tatis. This does happen, as you Yankee fans know - teams only focusing on a top prospect in a trade. Gerri Cole went to Houston because Pittsburgh was unable to pry Gleyber Torres from New York. San Diego has at least 10 prospects ranked higher than anyone in the Sox system, but if both teams inquired about the same player and they offered their #10 and the Sox offered Chavis or Hernandez, we get the player.
But bottom line - there are teams making zero effort to get better. But half of those 8 teams (at least) are making effort, just not with the results right now. If/when Harper and Machado actually sign somewhere, the fallout will become more attention to Keuchel and Kimbrel. Expect Chicago and San Diego to be involved in one of those waves.
But yes, Baltimore, Detroit, and Miami and maybe a couple others are a disgrace right now...
