What advice can anyone give me on how to be more explosive off the dribble?

now i've worked really hard on increasing my speed of the dribble, my first step is a muha. but if u watch some people like allen iverson, tony parker, baron davis how explosive they are off the dribble and how the defense cant react to them that's how i want to be, the handle is there, i can finish at thr rim but i just wanna be a good 2 or 3 steps quicker than i am now. suggestions anyone???
