No, not so much, especially in the final with 6 couples on the floor.
But... the couple crashing into the one with the blue dress does have awful lot of crashes almost every comp he dances now to think of it.
Check Russian championships 2012 final, previously stated couple is involved in alot of crashes there.
He has also crashed into me a couple of times very randomly...
I just experienced a back to back collision in Open Smooth at Heritage. The other couple was dancing "backwards" against the line of dance to do a cool shape in front of the judges and ran right into us - because of the crash - neither one of us was able to do our dips etc. This is why floorcraft is part of judging - you can't always avoid a crash but, you shouldn't cause one if you can avoid the traffic.
