Wait, if the team at the top of the East is not Atlanta then they claim it. If the team at the top of the East is Atlanta, then the team that qualified is the highest team in the Supporters' Shield that otherwise hasn't qualified (regardless of conference).
Correct. And the 3 teams on top the East currently have a nice cushion on the 2nd place team in the West. So it’s pretty probable now the top 2 teams in the East now qualify.
