Yeah unfortunately all their big guns are older and don't match up well in fast paced hockey. Guys like Panarin, Kane, and Zibanejad all prefer to slow things down and play more east-west hockey, but that's hard to do against a team with the forward speed of the devils. The back pressure was causing serious issues, particularly for Panarin.
There's a reason their best line at 5v5 was the kid line. They play more of a north south game and that was much more effective. The Devils absolutely blew the doors off the Rangers without that line on the ice at 5v5:
With the Kid line:
51:17 TOI
2.88 xGF/60
2.25 xGA/60
56.2 xG%
Without any member of the Kid line:
208:32 TOI
1.90 xGF/60
3.21 xGA/60
37.1 xG%
Without the entire Kid line:
280:53 TOI
2.16 xGF/60
3.32 xGA/60
39.4 xG%
