The Thunder already know Wallace can defend at a high level. He averaged 8.6 points, 3.1 rebounds, 2.6 assists and 1.9 steals across 77 regular-season appearances last season. Those numbers do not completely capture his value, but his postseason shooting provided an exciting glimpse of his next step. Wallace made 48.4% of his 3-point attempts during the playoffs, according to StatMuse. If that improvement carries into a larger offensive role, Oklahoma City will no longer be negotiating with a defensive specialist. It will be negotiating with a potentially elite two-way starter.
