I'm not really arguing that players didn't use steroids. I'm sure tons of them did, I'm arguing about their effectiveness for helping you hit for power. I absolutly believe they help you recover from injury. I'm arguing aginst big muscles = better.
There in lies my ultimate point is this, a baseball swing is too complex a thing to be oversimplified into, more muscles = better.
Cosign to all of this.
Bat speed is all about creating torque through the coil and separation of your shoulders and hips.
Strength could never really hurt you, but being flexible is key.
