With four NBA championships, two coach of the year awards and a team that's one win shy of the NBA finals -- not to mention a winery in Oregon -- Gregg Popovich sure has a lot to smile about.
But he doesn't.
At least not often.
The legendary Spurs coach is known for his crossed arms, hard scowls and burning stare-downs. Come game time, he's as jolly as a drill sergeant.
Every once in a while, though, he will crack a smile. Even if he's trying hard to fight it, a little ray of sunshine sometimes slips through the gaps between his teeth.
Kens5.com sifted through more than 1,200 photos of Popovich on Getty Images. We found about 40 of him actually smiling. Click here to take a look!
