Reality Check
Keepin' it 100
Why is Brock not on TV instead of a house show match? Or are they just worried about filling some seats and getting a good amount of tickets sold? Unless they are at some big stadium/arena type thing then I don't see the need for them to waste another appearance by Brock on a match that wont be seen on television.
It might be a WWE Network event special, which in that case, he'd be brought into the fold to help with filling seas and potentially draw in new WWE Network subscribers.
