How to prove to my coach that I can start?

My basketball coach doesnt have me in as a starter and I think I should be. The person that starts in my place doesn't know the plays, takes REALLY bad shots, doesn't really try hard, and horseplays. I'm kinda laid back and I do my job. I practice everynight after practice too. Just any tips during practice to boost my chances of starting.|||Maybe he sees you as a 6th man, More and more 6th men are becoming more important and very often 6th men as classed better then some starters|||talk to the coach and ask him his opinions on why your not starting, also, work extra hard in practice and make it obvious that u really care|||when u get in games prove it|||Posterize the n*gga that should teach him not to mess with you
