I think they're actually very much improved with Lin in the lineup...
Sadly, you seem to be correct, even though the sample size is quite small. It looks like they're going to get quite the challenge from Sacramento next year.

But the difference is Sacramento might actually get two top-7 picks in this draft, which could really help them next year.
I'm seeing Tatum and Ntilikina going to them at 6 and 7 right now, so they could have a really nice young core of Ntilikina, Hield, Tatum, Skal, and WCS. That alone should have them as good as Brooklyn, let alone their other vets.
Lopez is almost certainly traded this summer, too, so I think Brooklyn will still be the clear worst team in the league next season.
