At the risk of ignoring the "no negotiation" aspect...I think the Nets would be much more interested in having Daniels in that deal than Herb for age AND style reasons. And I also think the Pels, given their Phase 3 status if they suddenly added KD... would prefer to keep Herb than to keep Daniels. Win/win for both sides. I don't consider Herb a preference for a Phase 1 team, which Nets would be if they dropped KD.
FWIW: My small group of professional arguers decided a while back to rate NBA teams by Phase based on the following. Phase 1...tanking or severely rebuilding. Phase 2...borderline playoff team but nowhere near a serious contender (probably the worst of all Phases). Phase 3...a SERIOUS contender...immediately
FWIW (Part 2) Please..quit messing with my main man...Herb. By now, it should be apparent I'm a stone cold "Herbaholic".
