Russ is technically one of the best skiers out there, which is why he podiums at pretty much everything.  The dude is so good at everything it's crazy.  But,
The reason he doesn't get much loving on NS is because he's a comp skier and has the style of one.  There's a certain style to park skiing that is consistent and scores well with judges- lots of mutes, sw/forward dub corks, landing with feet wide etc.  And NS doesn't give that style of skiing much respect (which is fine by me).
If he used his talent do carve into relaxed 9 blunts, hed get a lot more loving on NS.
