Sheamus and Survivor Series

"I’ve seen a lot of Reigns vs Sheamus comments for the tournament final, with Sheamus cashing in after he beats down Reigns. To me this is completely illogical. Shouldn’t Sheamus, upon being told he is in the tournament, say "No thanks, fella" so he can be fresh and cash in on someone who wrestled 3 times that night? He should have no desire to wrestle in the tournament, right?"

I disagree. Why not take two chances at the title? If he wins, GREAT. He keeps the briefcase as a backup plan. If he loses, then he waits until a champ is crowned and cashes in on them.
