On June 22, 2017, Portland acquired rights to Zach Collins from Sacramento Kings in exchange for rights to Justin Jackson (Aaron); rights to Harry Giles III.
The Trail Blazers acquired Zach Collins' rights from Sacramento on June 22, 2017. Collins had been taken 10th overall after one season at Gonzaga. Sacramento received the rights to No. 15 Justin Jackson and No. 20 Harry Giles instead. Portland traded two separate opportunities to develop young players for one higher selection, a conscious choice to pursue the specific frontcourt prospect rather than maintain a wider group of draft bets.
Collins provided size and interior defense during Portland's playoff-era roster, including its run to the 2019 Western Conference finals. That team-specific contribution matters even though injuries later interrupted his continuity with the club. The C+ recognizes useful rotation value without assuming that drafting 10th delivered a durable All-Star. Portland spent two first-round opportunities on Collins and therefore needed his actual contribution, not just his pre-draft reputation, to support the grade.
Jackson offered a wing prospect with college scoring credentials, while Giles represented a frontcourt development swing complicated by earlier knee injuries. Both rights conveyed to Sacramento, and neither became the long-term Sacramento building block that would clearly outweigh Collins' Portland role. The Kings received two recognizable NBA prospects, so the return can't be treated as empty. Their D reflects how little lasting value the pairing produced for that particular club in the years following the draft.
Blazers Win. Portland earns C+ for the No. 10 Zach Collins rights and the defensive minutes he supplied. Sacramento receives D for Justin Jackson and Harry Giles at Nos. 15 and 20. The Kings obtained two players, but Portland realized the more useful contribution to its own roster.
