My 2016 RHP son just returned from the Headfirst Honor Roll Showcase last week (it was a phenomenal showcase!), where he pitched very well (mid 80's) and some coaches approached him at the showcase and he was told he stood out. In addition, ever since the camp ended, he has been receiving emails from college coaches. Some of them have been personalized indicating that they saw him at the showcase and asking him to fill out a questionnaire, while others look like been generic camp invites. He is an extremely good student (3.7 unweighted gpa with all AP and honors classes) and he is not really interested in the schools that have contacted him. We, nevertheless, thought he should be courteous and respond to them and not shut any doors. Consequently, he wrote back to the schools that sent him personalized emails and said he would look into the schools as it is early in the recruiting process for him. We are wondering if whether he needs to respond to the schools that sent him generic camp invites and whether he should fill out any of the questionnaires. I have seen on this website two schools of thought: 1) respond to every email and fill out every questionnaire; 2) don't complete the questionnaire if you are not interested because coaches don't want to spend their time recruiting someone who isn't interested.
Also, he did receive some emails over a month ago (and one two weeks ago) after he had done a prior showcase and he had not responded to the generic emails then either. I think he could have been interested in 1-2 of those schools but, again, because they seemed to be generic emails that could be sent to anyone and he was unable to attend the showcase, he did not respond. Is it too late now to send a response? Once you fail to respond in a timely manner, are you taken off the recruiting list for good or, if he sends a late response now apologizing for the delay, will they put him back on the list?
Finally, should we expect him to receive more emails come September 1? Is that an important date in the recruiting process? We are trying to gauge how much interest there will be for him from the schools he likes and I am not sure if, basically, what he has received is the total sum of interest in him. While he is a good pitcher, he is short (5' 9"), so I know many schools won't be interested in him for that reason.
