Yes, and he has the potential to get a lot of looks across other NCAA levels
Your son has a lot going for him. Use those "tailwinds" (academics, LHP, frame, etc...) to target schools that are looking for someone like your son. He still has time to further develop, and put some polish on his skills. Also, don't get hung up on the "D1 thing". As RJM stated, getting on the field should be the athletic goal. Folks get hung up on the D1 label because they don't understand there is a great big college baseball universe out there.
