Well sure, let's just remove the games everyone plays against bad teams and get a new adjusted record. Of course they're going to have a worse record when you remove those wins. That's what makes them a better team than those teams. 2 games under .500 is definitionally mediocre. They're in the middle of the NL. They can't be lowly if they're in the middle. They may not be great, but it's a stretch in my mind to malign them as "lowly" when that implies there's no middle tier - just playoff teams and the "lowly" rest of the league.
Regardless, we can all agree no one expected to have a 6-7 game lead on the rest of the division at the break.
