Michael Phelps Thinks Leon Marchand Can Break 4:00 In The 400 IM

Breaking 4:00 in a short course yards 400 IM is no walk in the park for the majority of the swimming population so when people started talking about how Leon Marchand 'could' break 4:00 in a 400 IM in long course it felt stupid to talk about. I agreed and decided to slow it down...until Michael Phelps said this.
