Probably...depending on what you are looking at. Single leg will enhance all those wonderful stabilizes much like using DBs will vs BB. But squatting or DL with 2 legs doesnt mean someone can do a pistol with bodyweight only....you are only as strong as your weakest muscle allows you to be...
for most sports which is Boyle's main focus single leg transfers more to the specific movements and needs....unless it is a specific movement that requires a 2 legged stance push...so for most athletes they need single legged training especially for power, injury prevention, acceleration, deceleration and change of direction.
