Ben ,
As speaking from experience , my son started this past season at Varsity as a freshman in 29 games , he started at the 8th spot in the line up then moved to the 2nd and 5th spot mid season, and ended up at the 3rd spot in our Region game, most of the advice is true, you have to work hard , you must treat framing and blocking like a art(take pride)! I wasn't so much on pop time for my son , as I was for arm Strength, he was @ 80 mph from the chute, don't know what the pop time is, ill find out next week at Area code tryout, we couldn't care less what everyone thought about size, they all said he was too short ,too skinny , etc, what they didn't know that he just started catching lol, he is a center Fielder by birth, speed kills , and I never had let him pitched till now, Weds will be his 1st pitching lesson( funny how things work)I know he throws hard, I always was about arm care, and bat speed and getting better, don't get caught up in anyone else ,stay within yourself.
if your were my kid , I would say work on getting better at more than one position, and if you can hit you wont sit!
