You're absolutely wrong. For instance, Jimmer Fredette can hit 80 out of 100 shots from the NBA 3-point line. Did you see Kevin Durant during the Olympics? Durant would probably have made about 80% his 3-pointers from the college distance. Many pro players, here and in Europe (Juan Carlos Navarro etal) could easily outdo what this kid did. He couldn't even play for a division 3 school UW-La Crosse (my old college), so he transferred to Grinnell just to be able to play. The whole thing was a farce of gigantic proportions. Also, in 1954 Frank Selvy of Furman scored 100 points in a game with no three ball. Selvy went on to play in the NBA and was a far superior player to Taylor.
Again, you totally ignored the time element. Why?
He couldn't even play for a division 3 school
Irrelevant. I played Division 1 basketball and firing up a shot every 20 seconds for an entire 40 minutes would be extremely tiring.
