Pretty solid-looking butterfly, one of the main things you can see right off the bat, is what is going on with his legs. You can see here, on his Down Kick frame how his right foot is a little higher than his left as he goes through his kick. There’s just an uneven balance consistently seen so there’s a little bit of a separation. If you coach young, age-group swimmers, a lot of times their Butterfly stroke is a little bit more of like a survival stroke, it’s not the best technically, and one thing that needs to work on or this guy needs to work on is having a better Dolphin Kick that it is symmetrical side to side. The right foot or the left foot raises to meet the other foot and space, here, between his feet and his knees, is minimized so that he’s kicking down with like one fin versus two feet.
