If Dolan doesn't decide to rebuild with great minds ASAP, as in next year, it just won't happen. He poured 1B into the renovation and has less than 10 years, I'd say 6 or 7, to guarantee MSG stays where it is. He needs asses in his ****ing seats. He'll keep attempting to build around names.
If Melo leaves, I don't think other names are going to want to come here.
And forget about a guy like Phil Jackson coming in and running the organization. He'd never work for Dolan, knowing any autonomy guarantee wouldn't be worth the paper it's written on.
