Right now all Jackson can do is focus on what he's already done well. There are many ways to re-build. Some teams do it by tanking and working through the draft. Other teams use it to get some veterans in free agency and 1 or 2 young draft picks. We're using the latter strategy. Jackson has to stick with the plan and get aggressive in free agency this summer. Knicks should have up to 30$M in capspace. There are going to be players who are good starter worthy backcourt types who want to play for a team that's going to push for the playoffs.
Lopez/Porzingis/Anthony/Guard through free agency/Grant
Talent is talent. Last year's team had the talent for 35 wins at best. We came close to that. This coming season, it comes down to free agency and what Porzingis/Grant play like. I think we can hit 45 wins if we make some good free agent moves. More than that, requires a major player like Durant, Conley, or DeRozan to sign.
For us it's all about how good Porzingis really is and how much we can improve through free agency. The only pieces that are in tact right now are Lopez, KP, Melo and Grant. I think the rest is still a work in progress and more is coming.
