#9 Money, Money, Money
Back when WCW was struggling to compete with WWE, their main advantage was a financial one.
With Ted Turner's backing, not to mention his vast media empire, WCW was able to coax many WWE talents away to their promotion.
Men like Macho Man Randy Savage, Hulk Hogan, Kevin Nash, and Scott Hall were all offered more money to work for WCW, which lured them away from WWE.
Now that AEW is trying to lure away their talent again, WWE can make certain that the past does not repeat itself. This time, WWE is the billion dollar company with a vast media empire, and they can use that financial lucrative muscle to keep their talent right in the WWE.
In fact, rumors abound that WWE is offering to DOUBLE any AEW contract. While this rumor is unproven, it does indicate that the WWE is planning to double down on retaining talent, which would be a smart move.
