10 ROH Stars Who Made It Big In WWE
6. Sami Zayn
Like his close friend Kevin Owens, Zayn spent a lifetime climbing up the ranks on the independent scene before getting his big break in WWE.
And despite spending most of that time donning a mask under the name El Generico (which made perfect sense for a Canadian technician), he still managed to carve out a nice collection of title gold, the most notable of which being two stints as PWG World Champion.
In ROH, where year-long world title reigns aren't exactly unusual, he never got his hands on the big one - just a Television Championship and a Tag Team Title alongside Owen (or, Steen, as he was known then) - but he did manage to put on myriad match of the year candidates, most of them with his former tag team partner.
