Think you need to rewatch the scene, it was 100% a push and not a dive. He's directly behind him with both arms out aiming for his lower back, it was a deliberate sabotage of the competition

Yeah I feel like there wouldn't be as much respect. One of my favorite parts about the show is the sportsmanship and respect everyone has for one another. I was really disappointed when >!miracle!< pushed the guy in front of him. Really felt like it tarnished the idea of the competition for me
