Come on Edge can still deliver good matches. Go watch last year's Backlash. It was Top 10 matches of the year. Last single match Kane had in Rumble 2018 was also good enough. Christian's return is a one time thing. And Goldberg was never actually a technical wrestling. Give him squash matches. He will do fine. I prefer him staying retired though. New Japan uses legends during Wrestle Kingdom every year. No one complaints there as your busy distracted watching 9 hours of wrestling, lol.
Problem with whole of WWE including NXT is them trying to be like NJPW, AEW, Indies etc. Seriously trim down those 20-30 minute matches to 10-15 matches. Trying watching any AEW pay per view. It will suck the life out of you with 40-50 minutes matches.
The only way they can deliver better product is bringing back brand split pay per views. With crowd gone. They don't need to worry about low crowd attendence. Yet, deliver an amazing product.
