I would trade 3, Crowder, the Mem and Clippers pick for Zinger. That is a lot of value, and I could be talked into including one of our young guards for him as well.
If the knicks played hardball, I would do 3, Crowder, and the Lakers pick. Basically it goes back to us "Only" having the BRK 18 pick. I guess at the end of the day, that means we traded 1 and crowder for a 7'3 unicorn who is super young, and a great fit for out system.
