We all are fans of the game, but sometimes it's easy to forget that these guys are not machines. They are human beings. Good for Love to open up about a real issue like this (Panic attacks, anxiety).
“After halftime, it all hit the fan,” Love said. “Coach Lue called a timeout in the third quarter. When I got to the bench, I felt my heart racing faster than usual. Then I was having trouble catching my breath. It’s hard to describe, but everything was spinning like my brain was trying to climb out of my head. The air felt thick and heavy. My mouth was like chalk," he said, adding, "By that point, I was freaking out. When I got up to walk out of the huddle, I knew I couldn’t re-enter the game—like, literally couldn’t do it physically.”
