Are you actually going to enjoy Brock as champion?

I have seen many people over the years say "if Cena wins, I am no longer watching" but they still watch each week anyhow.

Chance? Yes.

Likelihood? Probably not.

However, if and when Taker does return, I'll mark out like I do every time he makes his grand entrance.

I do. I wrote about this scenario in the other Brock thread. Whether it be at Summer Slam or a few months down the line when it's time for Brock to drop the title, imagine the pop if the lights cut out and the bell gong went off. It's the perfect way for them to have Brock lose without having to look weak to whoever will be beating him and solve the scheduling conflict issue. (Whether it's Cena at Summerslam or a new opponent a few months down the line.) I wouldn't be surprised if we get a Taker / Brock rematch next year after The Undertaker returns and distracts Brock enough to where he loses. If we ever do get that Taker/Sting match then I don't know how Undertaker can return without acknowledging Lesnar and Heyman. I could be way wrong of course but there's no harm in playing out these scenarios in my head lol.

If Brock does win and holds the title all the way through Mania on a very limited schedule then a lot of people will be complaining these next couple of months.

or just watch it on a live stream. 

I like that idea, it's great. It is a way for Brock losing without looking weak, and the pop would be insane.
