I don't see how that's true at all...
Just as an example of some of the matches he's had since the Goldberg Mania match:
- Fourway vs. Joe, Reigns and Strowman
- Survivor Series vs. Styles
- Survivor Series vs. Bryan
- SummerSlam vs. Rollins
- Handicap match vs. Mysterios
- Multiple relatively long, not good matches vs. Reigns (most recent match notwithstanding)
I also don't know if I'd consider the Day 1 Fourway or the Lashley match at the Rumble to be the same template. Unless of course the criteria is just that it mostly consists of numerous big dramatic spots, but if that's the case then you can pretty much put every Lesnar match since his return into that same category.
