Since his retirement from Duke, legendary coach Mike Krzyzewski has stayed very much involved in basketball. Coach K serves as a special advisor to the NBA, he’s still involved as an ambassador at Duke, and he hosts his own radio show on Sirius XM. Krzyzewski knows better than anyone about the changes college sports have seen in recent years, and he’s got a few ideas for how his former conference, the ACC, can stay competitive. “I’d like to see something innovative, like, I’d like to see the ACC and the Big East talk, and form a mega basketball conference,” Krzyzewski said on his radio show last week.
