What level are you competing at?
Not all great sprinters squatted and deadlifted. Michael Johnson and Carl Lewis did not squat or deadlift, and Carl Lewis hardly lifted.
Maybe they will help. But most athletes don't need ridiculous stength in the weight room, nor are O lifts necessary or magical either. Aim for some normal shit like 2 x bodyweight squat, 2-2.5 bodyweight deadlift, and 1.5 x bodyweight bench press and focus on your sport!
