A valid question. My point is that the mission of WWE Creative is to make Roman Reigns into the star they want/need him to be. Toward that end, they'll use anything and anyone to get him there.
A part of this goal involves Dean Ambrose. As you say, one could argue that Ambrose is helping Reigns stay relevant.......but the reason for is it that everything today is in service of Roman Reigns. At present, being involved with Roman is a goal to which everyone should aspire; the man is.....you should excuse the expression....The Chosen One. (Sorry, Drew)
That's not a criticism of Reigns, nor of anybody......it's what WWE is in the process of doing.
But yes, by himself I don't feel Dean Ambrose is a star of the future.....and Roman Reigns is. But at present, Roman needs Dean.
Does Dean need Roman? I say yes, because when the time comes that they're not working together, I believe Dean will be dropped to midcard status.
It's a matter of opinion.
Sally normally you and I are on the same page, so to speak, but I couldn't disagree with you more here.
I think it's blatantly obvious to everyone with eyes that Ambrose has and is being used to help put Reigns over as you said. So you have to ask yourself this question. Why are they taking one of the most popular guys on the roster and using him to put their "chosen one" over with the fans? Why not just put the title on Ambrose instead. The answer is simple. They need Ambrose he's popular and Reigns wasn't, so they are hoping that his alignment with Ambrose will get more fans on his side.
Now I'm a fan of Reigns, but how can he be the next top dog, if he can't get over by himself. We've seen the WWE use Heyman, Daniel Bryan, Ambrose, HHH and now even Vince McMahon himself to help him out. There really isn't anyone left. If Reigns can't get over with the fans after all that then he shouldn't be in the top spot. Now he has to stand and deliver, the buck stops with him.
So he now has the title and lets see how he does with it. Let's see if the WWE's faith in him is warranted. After watching RAW the other night, he did okay with Stephanie, but he has to bring it in the ring and on the mic. There is no really good heels for him to play off of, so this will be interesting.
As for Ambrose, I doubt he will drop down to mid card status. If they turn him heel then watch the fireworks go off. They have put a leash on him, and if they ever relax it and let him do what he's capable of he will not only surpass Reigns, he will surpass Rollins. Those that didn't watch him before he joined the WWE have no idea how good Jon Moxley actually is.
