A lesson every recruit needs to hear, from Shane Battier on his podcast Glue Guys with Duke's Jon Scheyer:
When you decide against a school that recruited you, don't just send a text and go silent. Pick up the phone to call & thank the coach. Tell them what their interest meant to you, even though you're going elsewhere.
Battier did exactly this as a senior, calling Tom Izzo, Steve Fisher, Roy Williams, and Dean Smith individually. Decades later, Izzo still thanks him for that call & he even had his own son do the same thing recently when cutting his college list.
It's an uncomfortable conversation at 17 or 18 years old. But it builds a reputation that follows you for the rest of your career.
