Maybe I'm not travelling in the right circles, but I've never known anyone to give up a potential sports prospect dog in favour of another more promising one. I feel like it's one of those old wives' tales that people who are doing agilliy/flyball/whatever The Right Way like to talk about behind closed doors.
More often I see people working to improve their sports dog's anxiety issues, fear issues, control issues, speed issues, etc.
