The whiteboard or dry-erase board has been a staple for coaches in huddles almost as long as basketball has existed.
They are both an instructional tool and sometimes the unfortunate recipient of a coach's anger, should he or she feel like throwing it or snapping it on his or her knee.
But this season Timberwolves coach Ryan Saunders hasn't used a whiteboard to draw up plays. Instead, Saunders has been using a tablet, and there are some analytical reasons for that.
"Seeing that players are spending a lot of times on their screens — video games, phones — I kind of dove into some research and some articles that say this generation may retain information better off a screen with some animation, too," Saunders said.
