In listening to Pope talk about it, the purpose is tracking to see when the players' productivity starts dropping. So, could they be in the game? Sure
But the question comes down to - is it better to keep player ____ (Oweh for example) on the floor knowing his production is going to worsen, or is the sub going to produce similarly to a 75% Oweh while he's getting a breather?
This way, you get rested 100% Oweh back on the floor sooner as opposed to burning him out more before subbing him, and then he needs a longer rest. Either way, he MUST come off the floor for a sub...so, is giving him shorter, more frequent breaks better for him and the team over the course of the game?
Honestly, considering how well this team has closed out games, it's hard to argue against the strategy b/c we all saw them surge against Duke, Zags, and UT last night.
