Aldo vs Merab was another.It wasn't Bautista vs Aldo, where Bautista walled and stalled against Aldo, who wanted to do damage.
Alex was walking backwards most of the time.
Generally, I also agree. Wall & stall should be punished.
There are wall and stall grapplers who should be punished, like some of Usman's fights, and entertaining grapplers, like Brady in his last fight.
Another fight that comes to mind was Jacare vs Jan.
A lot of wall and stall.
