Admittedly I didn't see much of the Pacers until the playoffs, but they worry me more than the Knicks right now. They are playing with swagger and have not backed down to a physical Knicks team. They play well at home, and they can play fast. Guys like Siakam and Turner would be very difficult for Horford(who has been great, but HAS to be tired) and Kornet to handle. And I could see Rick Carlisle outcoaching Mazzulla if it came to that (as would Thibodeau).
I enjoy watching the Pacers play. If they weren't a potential Celtics opponent I would find them easy to root for. That said, go Knicks tomorrow.
