If a team has depth, platooning is the way to go. Great teams have great depth. You don't have to have your best athletes playing both ways if there is not a big drop-off in talent when you platoon. Fatigue is a factor, and tired players will make more mistakes than fresh ones. If Corbin lacks depth, then they should definitely be playing the Smith twins both ways and keep them as fresh as possible through substitutions. But maybe the Smiths don't want to play both ways and maybe UK doesn't want them doubling their risk of serious injury. I doubt that their eligibility came without some conditions.
