How do I go about preparing for college basketball?

I've never played basketball in high school. I'm a senior at Kent State and I want to go out and do what I love. I've always dreamt of playing but I enjoyed wrestling then. Now I hoop everyday. If someone wants to say I'm not good enough, then prove it. I'm 6'4 about 171 and 21. I'm known for my hard defense but would like to figure out what things I should be doing to prepare myself. Simply, this isn't the question of whether I'm good enough because I know I am. This is a question of how to prepare myself in the best way to dominate even more than I do now. As a add-on if you have something negative to say, say it. I breathe and eat off of that. I love the haters. Make me prove you wrong.
