#4 Inability to perform in long matches

Since breaking the streak in a 25 minute-long match, Lesnar has never crossed the 20 minute mark in a one-on-one match. The two matches which crossed the 20 minute duration are the Triple threat with Cena and Rollins at Royal Rumble, where Lesnar stayed on the floor for a sizeable part of the match, after being put through a table by Rollins, only to come back during the fag end of the match to win it. The other match crossing 20 minute limit was the fatal-four-way at Summerslam 2017, where Lesnar was carried to the back on a stretcher, after being on the receiving end of Strowmans Powerslam, again to return a while later to win the match.
If we were to compare the champions of the respective brands, since his debut, the average duration of AJ Styles' PPV matches ( not including tag team matches) is around 21 minutes, while the average duration of Lesnar's matches, during the same period, is just over 10 minutes.
