ANN ARBOR, Mich. -- Michigan State athletic director Mark Hollis and his peers across the country try to teach their student-athletes to think before they tweet.

Hollis learned the lesson himself this week.

Hollis sent a message on his Twitter account to Michigan point guard Trey Burke, extending advice to a standout who is pondering staying at a rival program or jumping to the pros.

"If I had to do it all over again, I would've made it a general tweet," Hollis said Thursday morning in a telephone interview with The Associated Press while traveling to New Orleans for the Final Four. "It was probably unfair to direct my message to one person going through a process that I think has failed a lot of student-athletes."
