First, I'm more on the side of Daniel Bryan not winning cleanly. As much as I would love for that to happen, I just know it won't, small packages don't count as clean wins in my book. Second, if that were to happen by some chance I wouldn't be as mad as if he won in an unclean way. Let's say if DB won using the steel turnbuckle, he doesn't go over Cena, but he does get the WWE Championship, at least until Orton cashes in. If that happens DB is practically left with nothing where on the other hand if he wins cleanly, at least he has the clean win under his belt, which at this point it seems more important to beat Cena cleanly than hold the WWE title. I just don't think the belt holds as much weight as it did in the past. I mean CM Punk hardly main evented PPVs when he had it and took second to Cena.
So yeah in short, I would be okay with it because Bryan would be able to walk away with something even if he beat Cena cleanly, even if Orton cashes in
