Absolutely follow up with an email and thank you. Then do it again....and again....and again, until 1) they tell you to stop or 2) see #1 Sounds crazy, but in some cases, you just need to keep it up...maybe something comes of it, maybe not, but if it's a school that he's interested in, why not? Update them with any new info...new velocity number, HS schedule, summer schedule, etc. My son emailed some coaches 2 dozen times and never got so much as a thank you. Was it worth it....who knows....maybe they were reading it...maybe they saw him at showcases and he didn't fit what they were looking for, but it only takes a minute to send one, so why not?
