Be patient. It is hard not to panic. I remember being exactly the same thinking, my son just killed it against other D1 powerhouse commits, why did this coach just watch and not offer? Some schools are looking for specific things. Some schools talked to my son almost weekly for a year and never offered. He didn't commit until August after his sophomore year. I think for him, the number was 91. He had a couple offers before while hitting 90. He hit 91 3x and for the first time and he had guys calling all over. Who knows what specific thing they want to see from your son. What I have learned is that you can't control any of it. Give him opportunities and what will be will be. Good luck. You have plenty of time.
