Perhaps the best aspect of this year's team (and our teams in recent years) is that we're a very good road team. That's not common in the playoffs. We're 4-0 this year.
Contrast that to the Knicks-Pacers series, where the home team has won every game. Even the 2008 Celtics team didn't win a road game until they played the Pistons in the ECF. If we hadn't won a road game this year, this team would be labelled as mentally weak. We've had two bad game 2s at home, but I don't see how any fan could reasonably complain about our team's performance in the playoffs so far this year.
This team has what it takes. If we can play well at home with Porzingis healthy, we'll be hanging banner 18.
