(THEDAILYBEAST) — Barack Obama is a bad coach in the U.S. military war against ISIS, according to legendary Duke basketball coach Mike Krzyzewski, because the President is advertising to America’s enemies that the U.S. won’t use ground forces, giving the other team an advantage.

In previously unreported remarks at the Association of the U.S. Army conference last month, Krzyzewski told an audience of hundreds of military officers, defense contractors, and Army supporters that Obama has disrespected the U.S. Army by not using its infantrymen to fight in the war against ISIS. Making matters worse, Krzyzewski added, was Obama’s decision to reveal America’s playbook to our enemies by publicly declaring that the United States will not use “boots on the ground” in the current fight against ISIS.

“I know it’s upsetting to many of you when you hear ‘no boots on the ground.’ It upsets me too, because that’s like saying I’m not going to play two of my best players,” he said in his speech accepting the 2014 George Catlett Marshall Award, AUSA’s highest honor. “Because that’s what you are trained to do. And for decades and decades, the fact that we are a free country and we don’t play home games here is a result of having boots on the ground. That’s the problem.”
