Val is one of those wrestlers who the WWE didn't really give as many chances as they could have compared to various other wrestlers they tried hard to push. I can think of one time they tried to push his as at least an upper card wrestler and that was his match and feud with Mankind.
When he was Chief Morley, he was one of the top heels but nowhere near the title scene. The moment that ended, he was quickly back in the mid cad, and soon out of there save for a match here or there.
This really wasn't Val's fault; he's a decent wrestler and obviously can cut a decent promo. It's just the WWE didn't know how to properly use him.
Unfortunately, his star status has faded to that of slightly above a jobber. Having a reputation like that is hard to get out of once you are there.
That said, his win over Daniels was idiotic. Daniels was in the main event scene just the month prior as was pointed out. Furthermore, Daniel had beaten world champ A.J. Styles. That means in theory, since Val could beat Daniels, he could beat Styles, and therefore was a realistic contender for the world title.
Now, had he come in basically saying he was ready to turn the world upside down and prove what he always knew he was, that is one of the best wrestlers around, and then beat Daniels, I would have accepted that win a little bit more as would have several other fans.
That all being said, Val coming in was similar to D-Lo Brown a few years prior. He probably won't be used much, and if so will probably at best have a big win, then quickly go on a losing streak. From there he'd fade away, most likely to be an agent.
