4. HIDEO ITAMI: NJPW
Hideo Itami (Kenta Kobayashi) joined WWE after being one of the top guys in Japan for nearly a decade. However, he never found success in WWE, as he was plagued with injuries throughout his NXT run. His main roster stay was underwhelming and he eventually left the company in early 2019.
Itami returned to Pro Wrestling Noah, and made his NJPW debut in June. He joined the Bullet Club stable earlier this month, after competing in the G1 Climax.
3. TYE DILLINGER: AEW
Tye Dillinger (Ronnie William Arneill) stayed in the WWE developmental system for nearly a decade, before finally making his main roster debut in 2017. He stayed in the mid-card for quite some time and featured in feuds for the United States Championship.
Earlier this year, Dillinger requested his release and was granted. A few weeks later, he appeared on AEW Double or Nothing as part of the Battle Royal and was soon signed to the company full-time. Wrestling under his real name Shawn Spears, Dillinger is a fixture in the mid-card of AEW.
