If you are 14 and are touching 85 I would think you know you throw well above average for your age. Two things would indicate this. You throwing harder than almost all of the guys you play with or against and coaches lining up to kiss your rump.
There are JC and small college programs that have one or two guys that throw harder than 85.
I am not saying it is not true. I am just saying, despite what You Tube and special select blah-blah tournaments on TV may have you think, hard throwers are still rare. If you are 14 and sitting, say, 82 and touching 85 that is in the top few percentiles. If no one has said anything to you about it you need to get your numbers checked.
