The Cleveland Cavaliers did not have nearly enough spacing in 2018-19, and even when Kevin Love (who only appeared in 22 games, per Basketball Reference) was fairly healthy, they still could have used more.
Head coach John Beilein‘s offense, which is going to be predicated on Collin Sexton, Cedi Osman and likely fifth overall pick Darius Garland creating for themselves (and hopefully others often) via the pick-and-roll, will be at its best if quality perimeter shooters on the wing are placed around primary playmakers which will enable ball swings to be more effective, and Love, of course fits into that as well as predominantly a stretch 4.
