Are you guys 10 years old? Not every pro can do every flatground trick, a lot of them aren't even that good at flat. Anyone remember in the early ones when they got P-Rod on backside flips every time? (he did learn them later on) People have their strengths and weaknesses. Sure Nate Greenwood was a bit off on the switch flip game, but he was also playing against Felipe Gustavo (insane at flatground) and he did start off landing a bunch of shit with good clean style.
Remember dudes, just because you can do a mobbed switch flip and some dude misses it in a BATB game doesn't mean he sucks just as bad as you do.
