it is part of what makes it exciting. if Jeremy Wray's water tower ollie had a net underneath, it obviously would not be as gnarly. adding more flips, shoves, stances, rotations in and out of pinched grinds is not interesting to most people = doesn't generate as much revenue.
Nyjah is obviosuly aware there is a connection between good clips and earning cash. interestingly enough, if you watch the tour video he put out recently he talks about greed. but he is talking in the sense of trying to add more complicated tricks to the end of an already banging line. this was before the first slam. a trip where they went with homeys with days build in between skating to actually just take it easy a bit. In the end though, his greed will be his downfall.
