Chelsea Green is a walking mistake in the ring, and even her "Jumping Killswitch" finisher is a mistake.
the only reason WWE pushed her the way they did, is because they wanted something from her, like they had high expectations for Chelsea.
and when WWE-TKO management realized they couldn't get any positive returns from investing in her push, they brought Matt Cardona back only to humiliate him so they can fire both Chelsea and Cardona together.
