HHH is doing way too much talk about the end of the Shield for it to actually be over. I think Ambrose and Reigns add a 3rd member. Zayn, Ziggler, someone else? I think Sandow has the ability, would be tough to sell the personality though. This set up will let Reigns separate as a singles star (since they somehow are dying to do this) and maybe Ambrose plus the partner can be tag team contenders. The other way to look at it, as already mentioned, Reigns still needs a mouth piece. Imagine if we could get Reigns vs Cena? Would the match ever end, or would they both just keep becoming more Super?
I think this is great for Rollins. He's always been the best overall talent in the Shield IMO, and now he can step out and show off his athleticism. JR has been comparing him to a young HBK and I think that's rather fitting.
