It's no secret that the 6'7" forward has large hands. However, it's much easier to see just how big when they are compared to another person's hands.
This is what happened when Leonard met a female fan:
Here's a little bit of background on the situation:
She saw him and Corey (Joseph) shopping at the store she works at in Dallas. He was reserved at first so she was talking to Corey a lot until she asked him why he was so shy, then he said, "I'm not shy, I'm talking now aren't I?" After that Kawhi opened up and was friendly.
It looks like Leonard was able to connect with the fan, perhaps thanks to his large hands.
