She Can Have Better Matches
Guys, let's be honest: Carmella's not the best wrestler ever. I liked her match against Nikki Bella at TLC, but that was nearly two years ago. I don't really remember any of her matches since then, barring the first two Women's Money in the Bank matches where she won both of them, but they don't really count. That's like saying Bobby Roode's best match was the Money in the Bank ladder match, or that Curtis Axel's best match was the Royal Rumble.
Imagine that Becky Lynch faces Carmella at SummerSlam and beats her. That allows for so many good matches. Becky is simply a better wrestler than Carmella, and she is also good on the mic. Another Becky Lynch title reign would do wonders for the Smackdown Women's Championship.
