You're going to have to explain that better. First of all, I don't think you can buy the actual index (SPX) but you could buy a future on it. Do you mean SPY? VOO? Second, I haven't heard of decay of unleveraged ETFs. And even for leveraged ETFs it's at least controversial to say it's a real phenomenon. Third, in what way does borrowing to short the index help you, given that you have to pay for the privilege anyway?
