Yes pairing him with JAS was a long-term booking decision, putting him with BCC would be maximizing what is the best for him in the short term. Which would be find if he was in his upper 30s or in his 40s, but he's 23. You got to put him in the position where he is forced to improve his weaknesses even if it's not the best thing right now.
If you think someone is going to be a star one day, you do what it takes to get him to that level when you need him to be at that level, not wait until you need him at that level and then realizing he's not able to get the job done. If he's not ever ready to be at that level, then so be it, not everyone works out, but don't put yourself or the talent in the position to fail because you're always chasing the short term gains.
I mean that's kinda the same damn reason why WWE is where it's at now. For years now you've only had like 5 people booked as regular threats for the top title and all five of them are part timers or special appearance type talents in Lesnar, Reigns, Rock, Cena, and Goldberg. And they've built up Lesnar and Reigns to be such huge monsters it's frankly unrealistic for just about anyone to beat them. Like look at Summerslam, it took three fukking people beating up on Lesnar and then piling a bunch of shyt on top of him for Reigns to win a last man standing match. You expect anyone to believe that smaller guys like Riddle, Rhodes, Owens, etc. are going to be able to beat him without help?
They keep chasing the short term numbers like viewers, ratings, merch sales while not focusing on building up a collection of talent to carry and grow the business over the next 10 to 20 years.
