LOS ANGELES — With his team nursing a two-point lead at the start of the third quarter Sunday night, Stephen Curry took his seat on the bench, grabbed a box of popcorn and munched his favorite snack. A short clip of the scene rippled through the blogosphere, prompting many to poke fun at the no-stakes nature of the All-Star Game. A year after one of the sloppiest showcases in recent memory, however, Curry and his fellow All-Stars showed that this exhibition can be about more than matador defense and acrobatic dunks.
