Please note: In NCAA-speak, a "contact" is anything beyond "hello."
As a general rule, the NCAA sets aside a formal contact period in the late summer/early fall, another in March and another in April. Teams and coaches are limited to 130 person/days of recruiting during the academic year, and get two additional evaluation periods during the summer.
Here are the official dates for the 2010-11 NCAA Division I Men's Basketball recruiting calendar.
