It looks like it is otherwise. If our magic number is 3 with NYC, then if they draw they only drop 2 points and we still need 1 on Saturday. In theory if they draw on Wed, then they win out and we lose out then we are tied on points and wins but GD is the next tiebreaker. We have an impossible advantage in GD, but it is still statistically possible so we would not clinch.
If Van or Atl drop any points on Wed, then they are done. Looks like they kept up their wins recently and stayed closer to the shield race.
If we win on Sat its all done.
