If the intention is to just tank the best way to do that is not just getting rid of Chris Kreider but moving on from Mika Zibanejad too. You really want the team to collapse you do things like that. At the same time I don't think a hard charging motivator like David Quinn should be your coach. Might as well have kept AV around.
The Rangers have no intention of tanking and they certainly didn't try to tank last year. They played hard right up through the last game. They will do that again next year. Whether that means making the playoffs I don't know but I expect they will be better. One should expect that guys like Chytil, Howden, Andersson, DeAngelo, Lemeiux, Buchnevich, Pionk and Georgiev will all improve and Kakko (Hughes) to be a big addition too along with Kravtsov, Fox and Shesterkin and maybe even Rykov. It's going to be a very young team but also pretty talented.
