After Turner agreed to sign with the Blazers in July, Stevens received a phone call from the wing’s college coach, Thad Matta, who shared the news. Turner says he tried to contact Stevens, too, but the Celtics boarded a plane to visit Al Horford in free agency around the same time. Maybe the phone call failed to connect. “He says he tried to call me when I was on the plane, but I don’t believe him,” Stevens said. “You guys believe everything he says, but believe it or not, I don’t believe everything he says.”
