Looked to me like Jr. had his fender in there and Vickers hit him first.
Can’t pass below the yellow...
I don't have a horse in the Vickers/Junior race but it seems to me two good drivers were fighting for the same spot and the laws of physics say that doesn't always work out so good.
What I do find annoying is the knee jerk reaction of a lot of fans to automatically blame anyone but JR.
