Yeah Hook is a non-entity. He was kind of interesting as a meme character that got over for it, but that was now...5 years ago? He hasn't improved a single bit, despite working under guys like Joe and Shibata, Jericho, his father. He's still under 100 matches in 5 years of being on TV, so there's reps to get he hasn't been able to get, but he also has improved at anything since his debut. The very basics.
You look at some of the guys he's worked with and like, he hasn't been able to learn better basics? The Hardys, Fletcher, Juice, Sting, CM Punk, Darby, Swerve, Jay White, RVD, The Bucks, Orange, Lucha Bros, Shibata, Joe, Mox, Jericho, Briscoe, Roddy, FTR, Christian, Claudio, Kingston. Maybe this new Opps heel run will see him getting a lot of in ring and promo time to improve but man you could plug the version of him from any year into any other year and it'd be the exact same worker.
At the same time I wouldn't say he's hurting the company because he barely does stuff anyway. He's had the benefit of the doubt due to his dad for long enough, he's gotta step it up.
