Yeah, they need to build up a few more people to make them look like credible opponents for Reigns. I'm sure Brock was just an "emergency" call given Orton's back issues, I don't think AJ looks particularly believable as a threat to Reigns especially with him losing so much lately and they already had a feud about a year and a half ago.Know the original plan was Orton but they could have replaced him with someone else like AJ.
Or start having Roman defend in triple threat or fatal 4 way matches to tease the whole he might lose without being pinned or submitted route.
Hell give us Bobby vs Roman.
Lashley would be great, they should also think about splitting the titles again if Reigns is only going to be part time from here on out IMO. I just looked over their roster page and other than seeing they have way too many women on the roster they also just don't have a lot of top level stars and I don't think that's all on Vince, I think there are a lot of guys there who just know how to do moves but don't really know how to be a personality on tv.
