GREENSBORO — Duke coach Mike Krzyzewski wanted President Barack Obama to know he was joking when he said Obama should focus on the economy rather than picking an NCAA Tournament bracket.

So Krzyzewski's wife, Mickie, sent a text message to former Duke basketball player Reggie Love, who is Obama's personal assistant.

“Reggie texted back and said (Obama) wasn't offended,“ Krzyzewski said Friday. “Though some of the staff was concerned, because they always have to be concerned.”
