There was talk that the new Major League Soccer playoffs system would have its faults, but after the excitement of the single-leg first round, that talk has faded away.
There were two matches that saw 4-3 scorelines, with the Philadelphia Union just topping the bill as they fought from 3-1 down to defeat the New York Red Bulls at Talen Energy Stadium, earning their first playoff win of their history. The clash between the Sounders and FC Dallas was also an instant classic, with Jordan Morris scoring a 113th-minute winner after the game went to extra-time, following a 3-3 scoreline at the 90-minute mark.
