I am sorry but I am calling BS on this firing and on Jackson. Unless there was a secret handshake between him and his former player ("I'll give you some head coaching experience, you will get paid, we will tank, and I'll let you go when we stink like we should")...which I HIGHLY doubt...the blame should go to Jackson.
He hired a guy with zero head coaching experience to coach a VETERAN team with arguably a top 10 player on the roster. Haven't we learned that this is kind of a disaster (see: Kidd, Jason)?
Then he brings in Robin Lopez and Aaron Aflalo and expects - with a good rookie and a not-completely-healthy Melo - to suddenly be competitive?
This is a tanking firing, pure and simple. I believe Melo is a goner for sure now. There is no reason to keep him while his trade value is still there, playing alongside a 20 year-old and some average NBA veterans, to try and grab the 8th seed.
