Matt Jackson in particular has been selling the same back injury he picked up in NJPW for 𝘧𝘪𝘷𝘦 𝘺𝘦𝘢𝘳𝘴. It's also encouraged the idea that Matt and Nick can't sell for toffee which is - respectfully - utter nonsense. As well as playing key roles in the founding of AEW, the Bucks' chaotic everything-everywhere-all at once style of wrestling - where they wrestle each match like their loved ones will explode if they don't fit in every single idea that pops into their heads - has led to some of the most wildly entertaining matches in wrestling history.
It's an intriguing question, as Matt and Nick Jackson have already crafted a legacy in the business few other tag teams can compete with.
