Wouldn't ~10minutes make this by far the longest Oldberg match? Pretty much the only thing he's done since his WWE return have been thirty second squashes, with the only exception being the Wrestlemania match, which basically only required him to take a bump or two as Brock did all of the work.
On the Undertaker side, all his matches since Roman have been... better. Namely because they've also been relatively short, like him squashing Cena at Wrestlemania. And much like Goldberg vs people like KO and Brock, Taker more recently had been paired with good workers who can help carry the match. As with the inaugural Blood Money event, where they wisely decided to pivot away from Jericho vs Undertaker; while Jericho can still put on great matches under the right conditions, he can't work a style that would make Taker look good at this point.
tl;dr: The idea of Goldberg vs Undertaker in 2019 is an awful "legend" appeasement for Saudi Blood Money; if they were going to do it regardless, as others have said, the only way it wouldn't have been a clusterfuck would be if the match itself was a two minute Spear -> Jackhammer -> Taker sits up - Tombstone -> Done.
