You are the evidence dweeb, you tell me the numbers.
Nobody in WWE can touch him that is for sure. maybe some shitty Japanese wrestler draws more in Japan or something
The fact that you have to rely on me to produce numbers and evidence only further makes me question why you assume Brock is head and shoulders above everyone else in drawing ability...
But anyway, it's pretty much what Bort said. He's an attraction but not to the point where they can really justify his high price-tag any longer, which is why one of the rumors concerning Brock and Vince's argument backstage is that Lesnar is upset that Vince is offering him less money on a new deal than he has on his two previous ones. This is of course all still just rumors at the present time.
PPV buys aren't what they used to be ever since the Network was launched, but looking at the folks who do still purchase PPVs and comparing buys...
Extreme Rules - 108,000 buys
Payback - 67,000 buys
Money In The Bank - 122,000 buys
Battleground - 99,000 buys (despite being a filler PPV with a thrown together main event)
Summerslam - 147,000 (the biggest PPV of the year out of all the ones on this list, so it's hard to tell how much of that number is off the power of Lesnar/Cena drawing)
Night Of Champions - 48,000 (Brock Lesnar's first title defense)
Hell In A Cell - 86,000 buys
Survivor Series - 100,000 buys (despite the entire Network being FREE to all customers for the entire month of November)
TLC - 39,000 (the free trial in November was such a big success in gaining new subscribers that that number should be expected to be lower)
None of this is 100% concrete since a lot of it depends on how many subscribers they had to the Network at a given time, but there wasn't exactly a huge bump in subscribers when Lesnar won the championship. You could argue Summerslam and NOC would have likely been lower without Brock's involvement, but how much is debatable. That Battleground did that type of number (especially up against NOC) is both astounding and appalling.
I can't be arsed posting a bunch of links to television ratings, but if you bother to look, his segments don't really do any better (or worse) om average than what other superstars and segments usually do in his place.
