i saw pictures of myself pitching and when i release the ball everything looks good, my glove is up i am over my front foot but my back knee is almost dragging on the dirt(like it collapses). Is this bad and if so what are the negatives of it?

I think that is OK. Without seeing you, that would tell me you are really using your legs and whole body to throw the ball. Take a look at Tom Seaver, Nolan Ryan and more recently Tim Lincecum. They all use their whole body and have their post knee close to the ground.

ha you are right there is a picture of seaver and it looks exactly like what i do except reverse cuz i am lefty.
