When Myles Turner joined the Milwaukee Bucks in free agency, the Indiana Pacers opted to run a center-by-committee to replace him. This included Isaiah Jackson, Jay Huff, Tony Bradley, and James Wiseman. All of them were going to essentially replace Turner's value in one specific area (for example, the Pacers brought Huff in to replace Turner's ability to stretch the floor and protect the rim).
However, Obi Toppin was another sneaky candidate to help make life easier for the Pacers post-Turner. He's not a traditional big man, but he has experience playing small-ball center, which might ultimately be his best role for the team.
