As of today, Rawley is now considered to be part of SmackDown as his bio has been moved to the SmackDown section on WWE.com. Based on the interaction on SmackDown, it looks like Rawley will be involved with Gronkowski on a regular basis going forward and it looks like he may be getting a push.
Rawley has had several start and stop pushes since signing with WWE as part of their developmental system in 2012. He’s been paired with Zack Ryder as The Hyper Bros and then split away from him when he was moved up to the main roster. They later teamed on the main roster but then he was moved to being a singles star and they tried to repackage him as a heel last year. That idea was quietly discarded several months ago.
Both Gronk and Rawley will be busy this week. WWE is teasing Rawley vs. Baron Corbin for WrestleMania and Gronk is scheduled to host both Mania nights on April 4th and 5th. WrestleMania matches will be taped later this week.
