Lucky … I’ll ignore the projectability. I’m guessing throwing high 80’s, maxing 91 they’re not looking for baseball after college. Being JuCo and transfer players they want to get it right when they make their move. They should be looking for the best possible baseball experience and education regardless of division level.
Are your son’s the top pitchers on their staff? Pitchers who have proven they can get college hitters out will get a chance regardless of size as long as the recruiting coach believes he can get hitters out at the level he’s coaching. It’s why movement and command matters in addition to velocity.
There’s a poster on here with a son heading into his 5th year season in a ranked program. He’s 5’11”. He’s not the star of the staff. He hasn’t been drafted. But he understands his role and is very successful at it.
Know your fit. Know your role. Good luck!
