Let's all just agree that Durant is going to get his 25-30 points no matter who we put on him. We can't stop him...period. That being FACT, we need to maximize our match ups on the other 4 Texas players...you know...the ones that we might actually be able to play defense against.
If we want to win, we will have to hold down the non-Durant 4 (see the NU-UT game - Durant still got his, nobody else had much). I'll say the key stat of this game will be....can we hold the other Texas players, combined, to fewer points than Durant scores. For example, if Durant has his 35, the rest of the team has 30. Consequently, regardless of Durant's number, Texas' total points will be at a manageable level (~60-70ish). Thinking along these lines, IMO, provides us with the best chance of winning.
To sum up...take Durant out of the match up discussion...it doesn't matter. What are our best match ups on the other 4?
