I'd actually say the Taker-Brock match is the only one on the card that could follow HHH-Bryan (Which is absolutely going to steal the show) and not bring down the crowd.
As far as that rumored order goes...I am not a fan of the Divas match being after Brock-Taker, but hey...I guess a cooldown match is needed.
Yes, you're right. But they probably didn't want to risk it.
Divas matches are normally between big matches just to give people a rest. Last year they didn't do it after Taker vs Punk and everybody was tired for Lesnar vs HHH.
