So, who dunit?? Me thinking #3, looks like he squeezed off Roczen toward Anderson, then hit rear facing side of Roczen's front tire locking it up, triggering the avalanche, then rode off to the pits. Duno for sure, go check it out and tell me what you think, would like to see a straight down verticle vid, but there doesnt seem to be one, what do you guys think?
