Rio debate - Women's 400m
Raymond KC Graham: Most attention from a Caribbean aspect will be focusing today on the women's 400 metres finals as we could see someone from the region going all the way in what is expected to be a cracker.
Andre Lowe: It's a big one and what that will bring everyone out of their seats! Allyson Felix desperately wants an Olympic 400m gold medal and Shaunae Miller is sure to make it difficult. The Jamaicans, especially Sherika Jackson, look really good as well. This should be fun.
Raymond Graham: As I said earlier in the season. Jackson would have been Jamaica's best hope for a medal at Rio and she has not disappointed as she looked immaculate in her semi-final. It will be interesting to see if she will improve on the bronze medal she mined at the World Championships last year.
Andre Lowe: It will be hard for her. She surprised even herself with that 49.83 personal best run and considering the type of season she has had with all the struggles and poor times, who knows what she can do here. I think the bronze is her best bet.
Raymond Graham: Felix has shown that she is ready for the gold despite Miller coming to Rio as favourite. She also has a big advantage as she is lane four and Miller in lane seven will have to run her own race seeing that the dangers are all behind her and the lane draw here could all make the difference.
Andre Lowe: Felix made a big statement with that dominant win over Miller in the semis. She is ready. She will win the gold medal. Silver for Miller and after her run yesterday, bronze for Jackson.
Raymond Graham: For the first time I will agree with you. Based on that run and with her experience I do not see Felix losing. The real battle could be for silver and bronze and I give Miller a slight edge here while Jackson, Hastings and Francis will battle out for bronze and I like Francis here for the bronze.
