3 reasons why NXT has gone downhill in 2019
#2 The tag team division
This isn't entirely NXT's fault, as Vince McMahon had a sudden, whimsical urge to call up the champions, give them the worst name change ever, and then send them into catering. So, typical main roster stuff. NXT has managed to make the best of a bad situation by capitalizing on the popularity of the Street Profits and giving them a great title win at TakeOver: XXV.
Yet, beyond the Profits, the division is disappointing. The Forgotten Sons remain as bad an option as they've ever been. The Undisputed Era remain good, and will probably challenge for the titles at TakeOver: Toronto II, but another tag team title reign from them, when they dominated the scene throughout 2018, would feel like a retread. Lorcan and Burch are a good pairing, but need some building.
Beyond that, the division is thin. There's nothing actively bad about it (yet), but it doesn't feel like must-see television.
