I know it sounds stupid, but it may be good that you didn't make the team this time around. You can take not making the team in two ways. A) You can be bitter and think the coaches made a mistake, and you may not get any better. B) You could use that as fuel. That is what I would do. All your fiends know you are good enough, so I'm sure you are. I would prove the coaches wrong and dominate the JV guys. When your coaches see that, you could move up do to an injury, someone on acedimic probation, or toward the end of the season when they add a couple JV guys. I can gurantee you that a good coach will bring you up to Varsity.
If you work hard enough, gaining 10 mph is very possible. If you want it bad enough, it will happen. I am not a very naturally talented player, but I worked my butt off for the skills I have. I never pitched an inning in high school because my coaches didn't think I threw propper and I was too short. That fueled me, and I tried out for Georgia Southern University ( a Division 1 AA school). I made the team as a middle infielder, but after my first year I tried pitching. My coach thought I had a descent arm and let me. I started throwing around 78-80, but I had horrible mechanics. He worked with me on it for about a month, and I threw around 87-89 at the beginning of the season.
-I am now serving in Iraq, and I use lifes experiences to fuel me. I have been in quite a few really bad positions, but I let peoples negative comments and bad situations motivate me. I haven't let anyone get the best of me yet, and its not about to happen.
-I will be back home sometime between June and November of this year, and I will be playing Pro baseball somewhere at some level. If anyone doesn't see it happening, I could always use more fuel.
-Long story short, Gotty use not making the team as fuel, and let me know how that 85 MPH fastball is doing on the Varsity team.
