Most players are bigger, faster and stronger because of the advancement in PEDs period or tech advancements, such as lighter equipment and faster turf. They also help recovery.
Tech includes things like allowing catching gloves, while guys like Largent caught everything without gloves. In tennis, the hitting power is because of faster rackets, not “technique” differences. In gymnastics, they added things like springs under the floor to add bounce.
With the “bigger, faster, stronger” with PEDs, there are trade-offs, such as they come weaker ligaments for the huge muscles or heart issues, down the road.
Hardly “evolution”…
