Seth is not a bad first name for Tyler. The last name is something that I feel could use a little tweaking, though. But hey, Nick Nemeth is doing fine for himself as "Dolph Ziggler." Perhaps "Rollins" can be used to connect with audiences. But yeah, I'd have even given him his first name as a ring surname: "God's Last Gift" Seth Colby. Given that SmackDown! likes the Hispanic audiences, Seth Lopez could have worked, as well.
It sounds like he had a good match with Michael McGillicutty, so good on him.
