Why d3 football

I chose to blog on d3 football, because I'm training to become a middle linebacker or fullback for a d3 school. I had multiple opportunities to play when I was fresh out of high school. I waited now I am a freshman at a community college, and I'm looking back and wondering why? People tell me that I could play better than some of those guys out there. I know I can I just have to want it. That's why I just started to train a few weeks ago.
