#2. Seth Rollins
Seth Rollins and Roman Reigns were promoted to the main roster together back in 2012 as two-thirds of The Shield. Over the years, Reigns has talked about how much he learned from Seth Rollins and Dean Ambrose throughout those first few years on the main roster.
Rollins and Reigns have been able to put on some fantastic matches over the years and when the former World Champion found out about his former teammate's leukemia diagnosis, he was visibly upset on WWE TV.
Whilst Roman Reigns was on the sidelines back in 2018, Rollins admitted during an interview with Iridian Fierro of La Ley 107.9, that he spoke to Roman Reigns regularly and the two friends caught up at least once a week.
"I stay in touch with Roman. I talk to him once a week just to see how he’s doing. Mostly it’s about that. At the end of the day he doesn’t want to worry about work, he doesn’t want to deal with that headache right now, so it’s about seeing how he’s doing and his recovery right now.
"It’s nice to hear from him, and once in a while he’ll have a question about how things are going [with RAW], but it’s mostly just two friends catching up together."
Roman Reigns and Seth Rollins are currently on separate WWE brands, but with the WWE draft coming up, there's a chance that the two men could cross paths once again.
