I just had to share this one with my husband, a high school basketball coach.
According to a new study, happy coaches help teams win. Researchers found that coaches who smile at players before the game begins actually increase the chances of leading at halftime. I think the key word here is "before" the game starts.
On the other hand, teams led by coaches with tense faces and stressed-out body language are more likely to end up struggling -- and losing.
Surely that can be true for every winning coach. Check out the gallery.
