I definitely like the way Triple H has been shaping the future, but he seems adamant about creating new homegrown stars and not bringing in people who may already have a name. Now, obviously Angle has had his demons. But he claims he's a year+ sober now. If the guy can pass the physical and the drug test, I feel like they'd be foolish not to bring him in.
Guys like Bully Ray, Kurt Angle, Jeff Hardy, AJ Styles, Samoa Joe, etc. all could be hugely beneficial to WWE, but dirtsheets are constantly reporting WWE doesn't have an interest in them. It's really stupid to me. Of course you have to plan for the future with your new stars, but I still feel it's foolish to pass up on proven talent that can make an initial impact and then use their star power to help build your young guys.
With Kurt Angle alone, you have the perfect built-in mini-feud with Rusev, one of the only guys they can market as a believable threat to Lesnar, and a dozen fresh match combinations with guys like Ambrose, Rollins, Ziggler, Sheamus, Wyatt, Cesaro, and Bryan, etc. And several of those could reasonably be called dream matches to some fans and Angle has enough legitimacy built up that putting over some of those guys would help them tremendously.
Why the hell would you not bring him in on a part-time schedule, get all those matches out of him, then throw him in the HOF?
