Fresh off winning his fifth NCAA championship and with three players projected to be picked in the first round of Thursday's NBA Draft, it's clear Duke coach Mike Krzyzewski is doing many things right.

And one of those things, the college basketball mastermind just revealed, is using a secret Twitter account to spy on his players.

"I follow guys. I don't want to be on Twitter because I don't care. I don't want their opinions. I don't need to show that I have X amount of followers. But I follow a lot of people on Twitter, under an alias," Coach K told ESPN.com on Wednesday. "I tell my guys I'm following you. Then if I see something, you text them, you gotta watch. But there are a lot of cool things that they do. I do like that they do it."

Coach K's watchful eye kept at least three star freshmen on the right track this past season. After winning big in their only year of college hoops, big man Jahlil Okafor, wing Justise Winslow and point guard Tyus Jones are all locks to be picked in the first round Thursday.

Okafor, however, says Coach K may not be as slick as he thinks he is — even if his handle remains a secret.

“Everybody knows,” he told FTW.com on Thursday. “When we’re on the bus, we always see his phone. He has the words really big. So we don’t know his Twitter name but we know he sees us on Instagram, we know he sees us on Twitter.”

Let this be a lesson for all wannabe Dukies: If you're a high school hotshot hoping to play for Coach K one day, he may well be tracking your tweets, too.
