#4 Seth Rollins – 26 years old
From one Shield brother to another. Seth Rollins actually made a name for himself in Ring of Honor as Tyler Black before he was offered a contract with WWE Developmental. And, much like Roman Reigns, he spent a couple of years there before jumping over to the main roster.
He was just 26 years old at the time and even picked up the honour of being the first ever NXT Champion on his way to the main roster.
