Question about prevent defense

I've always hated the prevent defense as it usually turns out badly. After the Bills/Chiefs game I saw someone make a comment that the Bills should have sent out LBs and DBs with no lineman. Then the Bengals basically played this way, few lineman and a spy, and it worked perfectly. Is this the answer to stopping high-powered offenses (with under a minute to play) or will offenses find a way to take advantage of it?
