Points (Wins/Draws) and Current goal differences:
NYCFC: 6 points, +6 GD
Cruz Azul: 6 points, +3 GD
León: 6 points, +3 GD
New England: 6 points, --
Seattle: 4 points, +5 GD
Pumas: 4 points, +3 GD
Comunicaciones: 4 points, 0 GD
Montréal: 3 points, +2 GD
This will come in to play in the semifinals and finals. The winners with the most points, followed by the best goal difference will get the second leg at home.
EDIT: I looked at the CONCACAF CCL rules, and points (3 for a win, 1 for a draw) are the first tiebreaker for hosting. Goal difference is the second tiebreaker.
I don't know how the competition is handling Cavaly's two forfeits, so I gave New England six points and left their goal difference blank.
