The Pacers are not good this year, and the whole goal for this trade is to focus on next year, and the goal should be is to have the worst record this season to lock yourself in a top 5 spot. This draft, you can get the 5th pick and still guarantee a potential franchise guy.

Pacers land Dereck Lively in hopes to be either future starting C or backing up Boozer, Wilson, or Ament. Lively is also out for season so you can have him rest and spend his time off learning the playbook. Pacers also add Jaden Hardy in which is just a cap filler, he might either just get waived or traded in a third team trade.

Mavericks land a secondary scorer for Flagg who will be able to relieve the aging Kyrie when he returns after the All Star break and PJ Washington. Mathurin is also on a expiring which will either help save money for next year or be able to bring him back on a Qualifying Offer until AD's contract is off the books after next season.
