10 Things That Would Happen If Conor McGregor Joined WWE

5. McGregor And The Undertaker

This would be a bold booking, but given The Undertaker's love of MMA, and the blockbuster value of the two names meeting, it could absolutely be on the cards for Taker versus McGregor.

The sell would definitely get people interested. Both are huge stars, and you can't imagine either losing. That's why it is money. And McGregor could have a field day on the promos against the Deadman.

The problem comes in the result. They could do it at Survivor Series, with McGregor winning. They could have it as one of his "Mystic Mac" moments, stating in a promo the week before that he'll finish Taker in under five minutes.

And that's what they should do. McGregor just blasts Taker with a ferocious UFC style attack, knocking him out with the left hand and covering for a pin. Taker could kick out right after three to save some face. They could then get his heat back by putting him over someone else the next month.

As for McGregor, he goes on to promos galore about how he slayed the Deadman. Again, that's the value, as more people are going to sit up and take notice if McGregor beats a legend like The Undertaker like that.

The thing is, in terms of being able to take WWE seriously, there's no way they can have a 51 year old pro wrestler beating a 27 year old MMA fighters.
