His butterfly reminds me of people swimming the 200 with a very long glide.
He obviously has the strength but he goes more UP than FRONT. But for someone (to have the audacity) to tell him what he's doing wrong, he could have been quite a fast flyer.
I met former Mayor and Civil Rights leader Andrew Young once at Emory University when I was warming up between sessions at a meet in High School. That was kinda of cool. He commented how fast and effortless I made it look.:D He swam in the lane next to me for about 30 minutes or so.
