It's really disappointing to see how badly Vince has failed the amazingly unique and dynamic characters in the Wyatt Family by destroying their credibility as legitimate heels by having them lose pretty much every feud they've been put in.
Going back to the OP's analysis. He is entitled to his opinion, but I'm not convinced.
I think Bray Wyatt is a phenomenal talent, who hasn't shown all he can do. He is phenomenally good on the mic and playing the character. He is solid in the ring and he has a good move-set for his character with room to grow.
Luke Harper is an incredible in-ring talent, especially considering his size. His look is great for his character and he doesn't need Bray Wyatt-like mic skills. His mic skills are about saying little but meaning a lot!
Erick Rowan is solid in the ring, and doesn't need strong mic skills. He hasn't shown all he can do but he is solid none the less.
Braun Strowman is obviously the greenest performer in The Family. He's there to be the BIG, BAD, BRUTE, obviously. He does fine when speaking because he just speaks as barbarically as he can and yells and scowls, which pretty much does the trick. In the ring he is obviously limited. I'd like to see him do a little more every week. Add in a scoop slam or military over head press slam or give him a match where he can toss around some jobbers to show off the fact he is actually quite strong!
The whole problem with the Wyatt Family, as many have mentioned already, is that they currently have little to no credibility. And when it's a scripted show, that's pretty bad because there is no reason for them to have no credibility.
Well, this is WrestleMania season and I have to say, I hope Vince is finally ready to give the Wyatts the solid push they need or at least provide them a way to continually save face and maintain credibility with each feud they are in going forward.
I hear Wyatt has a pretty serious back injury but hopefully it's only something hindering him for a few weeks. Hopefully the rest of 2016 will be when the Wyatts really build and maintain credibility. They need decisive wins over established stars. Bray Wyatt needs a few clean wins over established stars. Harper & Rowan can win the Tag Team titles. Bray Wyatt can win the IC title after hopefully getting decisive wins over many top stars on the way up and then hold that IC title for at least a few months. Yes, he can use heel tactics to retain and use his Family as guards but he has to be shown to be firmly in control and able to play successful mind games with opponents. It'll take time, though, because so much damage has been done to their credibility.
Time will tell if the Wyatts will ever be able to be taken seriously. I think this year will be the most telling of their career.
