What you would do? BASKETBALL?

Ok so i'm on JV in basketball. I'm a PF/C kind of guy, during practice this freshamn who is also a PF tells me i can't come in, i'm want to prove to the coach i'm better, and i willing to bet my Iphone 5 that i'm better than this kid, What would you do? I'm also 6"2 and jes 5"10. What would you do? He always tell me to get out when ever he wants in?

Play your best, regardless of who else is there with you. Always play in a way that you would want your coach to see you. Imagine he is always watching you, if that's what it takes for you to do your best always. Ignore this other guy. Do not do anything unkind or rude to him. If you really are the better player, let that skill get you the position. The coach doesn't want someone he has to keep an eye on or worry about.
