I think they're referring to the Boomer tweet where he said that Kadri wasn't interested in signing here now:

But there have been a lot of rumours since then that they're still in the mix. Boomer's tweet was also before the Huberdeau/Weegar trade which may impact his interest in signing here.
Friedman said on the recent 32 Thoughts that signing Kadri may help convince Huberdeau and Weegar to sign long term too. Clearly all 3 signings will be announced together.
