The Knicks have played a ton of close games. So you can certainly say they are battle tested. On the other hand, I also wonder how they'd look if a team actually punched them in the mouth and blew them out. How would they respond after that?
I'm not discrediting what NY has done, but PHI really choked two of the games (Game 2 and 4) and IND has also clearly looked rattled late in the last two games. I know we question Boston's ability in close games especially Tatum, but I still feel we should have a leg up on NY in terms of experience in those moments. That's where some of the smarter guys like Jrue, White and Porzingis can hopefully shine for us.
But ultimately, I love our group of White/Jaylen/Holiday outplaying Brunson/Hart/Divencenzo, and then as long as Tatum isn't a puddle we should be good. And that's not even counting Porzingis IF he returns, he's easily the best frontcourt guy between both teams and Knicks lost Robinson for the season.
