A Very Brief History of Men’s Swimwear.

[Torchwatch]

The coach to your son's swim team has 2 problems, first the swimmers in his squad aren't very good and 2nd their Lycra jammers aren't very good.
The 2nd problem can be solved by going over to swim briefs both for training and racing, this will cause those members of the team who aren't interested in improving to leave.
He can now put his attention into those left training harder and improving.
As the smaller team starts to improve and actually win races it will attract attention and gain recruits, even if they have to wear swim briefs.
If they still fail to improve they probably need a new coach.
