Philadelphia Union have dropped two points total in the five games since they fell on the road to Toronto FC. Along the way, they switched shapes and won without Jose Martinez. Then they lost Alejandro Bedoya and started Jack Elliott in midfield. They lost Ray Gaddis and didn't miss a beat. They leaned on Anthony Fontana and Olivier Mbaizo and Matt Real.
Many things could have stopped the Union's momentum in its tracks, but none of them did.
Jim Curtin has taken a team of homegrowns and veterans and melded them into a unit that steps in for each other with ease.
