Even with Favors' injury concerns, Utah doesn't win that first round series without him. Dude came up big in the playoffs even without being 100%.
But sure, if Utah can find an all-star FA that wants to join Hayward and Gobert, Utah could theoretically find a way to clear cap room. My problem with that, is that Utah already has a potential 60 win team that could be even better next simply with better health and some internal growth. Losing depth in guys like Favors and Ingles could end up hurting more than it helps.
Last time Utah made this kind of move was letting Boozer go and trading for Al Jefferson. Didn't really work out like we hoped.
Anyway, I'm not sure it's realistic to think we can catch up to the Warriors by moving players around. Unless we can get one of our stars at half price, then we just can't stack the deck like they have. Might be better to stay the course and wait for their salary issues to catch up to them, which they will.
