Jackson can't justify to Dolan, Mills or anyone that he's being unbiased and bringing back Rambis if his record is 10-19 or something like that as a head coach with the Knicks.
As I said with Derek before he got fired. I don't think winning less than half your games keeps you head coach. You're talking about possibly the one executive who would be the hardest on a coach because of the level he himself could coach. There's many organizations that would accept not so good coaching. The Knicks are not one of them. That's in part why Fisher was removed.
Rambis will need to win more games. He can't finish with 10 wins and come back. It would resemble Fisher's, which was a losing record. This is about getting a coach who not only runs the team properly, communicates well with Jackson but most importantly delivers the wins. Rambis isn't doing that so far. The only thing I've liked about Rambis is that he's been harder on KP and that will help him grow as a player. Too many people in NY in love with KP now to call out his flaws in his game. He's already starting to play better basketball. He may not show it with his shot making, but 11 FT's is what I want to see out of him. He's a mismatch hell and shouldn't just settle for the outside shot. Which is what Rambis is trying to get him to do. That's a major major asset from Rambis. He worked with many other top bigs in their early days and worked with Gasol in his best years in LA. He's worked well with Lopez as well. Rambis will rub off very well on KP in the long run. Not in the typical way, but in a different challenge him to be better way.
To be honest don't even think it matters all that much who is the head coach next year unless we have major talent. We need much much better guards. We won't make the playoffs when the two best fits are Jose and Sasha (which believe it or not, they are).
