Thank you all for the feedback thus far. Many things he has been doing were reinforced by your comments while others (i.e. weightlifting) was not even something he nor I have even considered yet.
He is a 7th grader on U13 so the feedback regarding the 7th/8th grade level was poignant. He is exclusively playing CF so position versatility is something that could be discussed and he can talk to his coach about a secondary position.
Again - thanks for all of the feedback. I'm so thankful I found this forum at this juncture.
