As the leader once you select a "lane" in the stretch you have to stick with it. Todd came off the turn a little wide and committed to a path that was off the rail, with plenty of room inside. Once Braxten moves in to take the vacant lane you can't come back over and block it. What happened after is incidental (putting a wheel under etc..) .
I think the focus of the inquiry and decision to DQ was based on the action very early in the stretch before the actual contact.
If it went the other way some would say bad call or whatever.
We wouldn't still be talking about it and would of taken the judges 2 watches, but we are talking still, and they took way longer than the 10 min replay video I've seen.
Was Canadian discrimination?
The US boys better watch their ass up north, because it's coming!
