I do, I just think at this point that opportunity has passed. Del Rio has proven to be able to find away to overcome every obstacle thus far (except Punk in a fair fight I guess) without having to resort to dipping into his wealth. He's clearly in the same league as Cena and Punk even before you account for cheating, and the cheating (or at least the underhandedness in matches with no rules) puts him over the top when it works.
I think at this point, resorting to buying opportunities is beneath the Del Rio character.
