I found MMA through Pro Wrestling, or at least through my Pro Wrestling friends. I come from Calgary, Alberta, one of the Mecca's for the gig. I've since moved on but some WWE style ideas get me interested. I think there's a way to do a tag team match, or even a mixed tag match and still get away with it. They wouldn't be able to switch participants in the middle of a round, but maybe they could swap between rounds.
I bet guys like Fitch and Koscheck, or Machida and Spider Silva, Rashad Evans and Keith Jardine, guys who train with each other, and face things with a similar mentality might like taking on fights together.
It would go something like this: Rashad Evans and Kieth Jardine VS Lyoto Machida and Anderson Silva!!! Jardine & Evans come down the isle together, get patted down and checked for foreign objects, lubricants, etc. They both get up on the edge of the cage, Evans goes in, and Jardine stands on the outside with his coaches, under supervision of those grumpy guys with the red coats. Silva and Lyoto come down to some Brazilian Samba, and same deal, but on the other side of the cage. Silva enters, Lyoto stays out. Silva and Evans fight a tactical, elusive battle, finding their rhythm in the middle and exchanging some solid blows. Right at the end of the round, Silva lands a sneaky right cross that staggers Evans, but Evans is saved by the bell. Round 2 starts with Machida and Jardine. They fight a methodical fight of Jardine taking the centre, pressing Machida, who retreats, then engages with his hands. A full 5 min. Now, With Evans still rocked, Jardine stays for the 3rd, and Silva comes back. Silva comes out, takes the centre of the cage and stalks Jardine, presses him up, and finishes with knees in the clinch.
It's safe for the fighters, as safe as fighting for a living anyways, and damn good television.
