Eric,
Do you have the answer to every question your kids ask, or do you encourage them to look up the answer and educate themselves on the subject?
You as well as others have been directed to the NCAA site on many occassions, however, you could use google and do a search, sometimes you just have to type in the question.
Can a college coach talk to a player if he comes to visit him at a game. Depends on what division, what time of year, etc. Coach May made a great post in another topic, sometimes this process is about personal responsibility.
However, I really don't beleive you come here for answers, you just come here to give updates on your sons recruiting process.
I simply typed in the question you asked, I found the answer (though I knew it), you might want to try to do some research on your own, perhaps not at work if you are busy. I am sure that you didn't need to have that answer ASAP!?!
It's just gotten to be old.
