Why the pelicans could do it: Julius randle is a power forward that can work in the paint just like zion even though he's less explosive. He very much makes up for it with his health.
Why the nets could do it: Zion even though he's very injured is a very explosive player, last season he played 62 games yet led the pelicans to a season as bad as a tanking grizzlies and a season worse then the tanking bulls.
(the two seconds are to pay the pelicans for taking on that terance mann contract, whether they choose to buy it out or wait for it to come off the books)
