It went on WAY too long, and I say that for a few reasons.
One being, simply, it didn't need that much time. Much of it was simply Brock huffing and puffing, making him look more like a moron than anything else.
Another, is that it had Brock speaking for way too long. Nothing against him personally, but I can't hardly take him serious as a heel when he talks so much, it just isn't very convincing to me. He should be the man who talks very little, and speaks with his actions.
Tonight, he should have just said a few lines, taunted Zach, and then tossed him down the stairs while he yelled out like a man beast.
