#17 The Miz
It's interesting to know that The Miz has been with WWE for 15 years. He's barely wrestled anywhere else. The former reality star did the impossible and has become perhaps one of the best WWE Superstars in the modern era. He's dependable and it's not far fetched to say he's a company man. It would be shocking if he ever signed with AEW. The Miz is WWE-bred and will most likely finish his career with them.
#16 John Cena
John Cena has been the face of WWE for more than a decade. He's been a multiple-time WWE Champion and is now embarking on a career in Hollywood. While he may show sporadically in the company, he will never ever wrestle for another promotion. It would be unthinkable, to say the least. John Cena still has one more WWE run left in him and it will probably be the last of his wrestling career.
