people claimed more teams would feel the need to make moves because they couldn't make them later.
then the dodgers, yankees, red sox and some fringe teams decided to just stick with what they have instead of paying rip off prices.
bumgarner would probably be moved in august once the fairy dust runs out on the giants. the yankees would have found their starter on the scrapheap and gotten by until the playoffs when you really only need 3 starters anyway.
the point is, mlb tries to fix these things and out think people who are paid to out think other people. it doesn't work.
now the teams that are shit are going to be shit for two more months and the ones who need help are just going to spin their wheels for two more months. fantastic.
