The Knicks have 8 guys on their roster for next season and are only $13m under the 2nd apron. They will almost certainly lose Mitchell Robinson, Landry Shamet and possibly Jose Alvarado
With Dolan saying the Knicks are not going to pass the 2nd apron, it means Mitchell Robinson and Landry Shamet are both almost certainly gone. Jose Alvarado has a 4.5m player option for next season, you have to think he will opt out and get a bigger offer and be a casualty of this as well.
Edit: The $13m mark above includes Jose Alvarado opting in and the cap hold for the first round pick. Thanks u/Legitimate_Cow_4166 for the correction. So if Alvarado opts out and they keep their first, it will be ~17m to fill out 5 roster spots, which is not as bad.
