Really good response from 2019Dad. Although I will add that as years go by the projectability gap declines. In another year the two kids above will be 6'3" 180 lbs and 6'2" 210. The 180 lbs kid may still be projectable but not to the extent they were 12 months back. If they are still throwing the same speed now (or 210 lbs guy is slightly faster) then they may be on a level playing field. I've got a lean AND young (for class) kid a little behind the class' top level but they generally have 6-9 months minimum on him (and some have 12+ months on him). I'm hoping the "projectable" label sticks to him for a little while longer. The good news is on the mound performance will be the final determining factor especially for college (my understanding is that MLB routinely picks some projectable pitchers - but you still have to be throwing high 80's as opposed to 95).
