I'm torn between "No, not even close" and "He's getting there." I do think Reigns has potential that hasn't really been tapped, or maybe it's just going to take more time and experience for that to come out. At the same time, the overall booking of his feud with Lesnar makes me feel, to some degree, that he's not even close. However, in my opinion, he's most certainly NOT ready for this spot.
If the reports of Vince ultimately writing his stuff for him are true, then all the blame can't be put on his shoulders. For the most part, I don't think Vince's booking decisions, especially for the top matches this year, have been all that spectacular and the ratings that Raw has been pulling in over the course of WrestleMania season may well reflect that. There's been so very, very, very little interaction, intrigue and passion between Lesnar & Reigns that I'm less invested in this WWE Championship match than at, possibly, any other in WrestleMania history. Bray Wyatt's done an excellent job on his promos and I admit that I'm genuinely curious to see how Taker looks, feels and can perform Sunday, but this intrigue doesn't yet ease any doubts as to whether or not the match will be lousy. I also think that Sting vs. Triple H could've used some more interaction between them, though I have enjoyed the tension and the overall storyline. I don't know if this is so, but I kept getting the feeling that much of WrestleMania season last year had more final calls being made by Triple H. I might be completely wrong on Trips being allowed to make more final calls last year, it's just that the overall atmosphere just felt a lot more energized and seemed more in tune with what we tend to see in NXT compared to the current WrestleMania season and the numbers from last year were where they're supposed to be.
