Tillman has a 4.0 grade point average, a 26 on the ACT and high-level character, said his head coach, Ryan Antoine.
"I was crushed about it," said Tillman. "Because that's where I really wanted to be: at Stanford. He (Anderson) told me good luck and said he would try to find out more about it.
"I was overwhelmed. At first, I didn't want to go play basketball - I had a game that night - and I didn't want to play. My plan was to stay in the house but Coach Antoine came and got me out of the house. I'm glad he did, because my teammates helped me feel better - even though they didn't know what was going on at the time."
Antoine talked about Tillman.
"Words can't even describe what type of kid that he is," said the West St. Mary head coach. "To be able to persevere through this situation, to be able to go through the things that he's going through...to go around and think that everything is fine, and then to get a call like that and still hit the game-winning shot in the basketball game...
"What God has in store for this kid is going to be great - I guarantee it - and whoever gets this kid is getting the complete athlete. The athlete who does well in school, does well in everything, and makes everyone around him better.
"The sky is the limit for him, and I'm very anxious and excited to see what happens with him in the next several weeks."
It's possible that Tillman won't sign next week and will defer his decision to a later date.
