IMO Clingan doesn't even need to win the individual battle against Edey (Edey's gonna get his points and will have the refs in his back pocket) - DC just needs to avoid drawing fouls and stay in the game long enough to neutralize Edey's presence, box him out, get some rebounds and create enough floor space for the rest of the team to get to the rim or hit mid-range shots.
And of course, speed up the tempo so Edey has to run the floor. Edey is better in the paint in half court, but Clingan can run the floor better than Edey.
We win as a team. No matter who the opponent, this team beats them by wearing them down. We stick to that and we win.
