#9 Brothers of Destruction Beat Up Sanity
The WWE has done very little with Sanity since their call-up to the main roster, so it isn't prudent to sacrifice them to two legends who have accomplished everything they needed to in this business.
However, from an optimistic perspective, being involved in a segment with The Undertaker and Kane would give Sanity a lot of attention. Also, keeping the brawl a bit competitive instead of a simple chokeslam and tombstone squash would be great.
An almost three-minute brawl with the veterans coming out on top at the end should both showcase Sanity as competitors with some credibility and be an awesome moment. The Undertaker and Kane can then cut a brief promo about how they'll make DX rest in peace at Crown Jewel.
