I also think in this particular race, Kessler broke off the line slower than desired , but was still okay and right about past the 400M mark, with solid position clearly on the outside of Engels...and not impeding him, gets slightly rubbed. then an outright arm push from Engels. That's the way I saw it, I also think bumped from behind? It's not on him to run faster there, the guy behind? Pass in middle of lane two.
