"In 2010, the Big Green eliminated tackling in all practices — even preseason camp and spring ball," reports The New York Times. "Coach Buddy Teevens likes to say that a freshman will play four years without being tackled by another Dartmouth player. The N.C.A.A. has since recommended dialing back contact significantly in practice.

"A couple of years ago, Dartmouth began using moving robots as tackling dummies. The tall, remote-controlled cones of padding whir along Memorial Field’s turf like R2-D2. Now, more than half of N.F.L. teams, several dozen college programs and around 100 high schools have these mobile virtual players, or M.V.P.s, Teevens said."
