The right strategy the NFL should use is to hire a bunch of top orthopedic specialists and have them analyze TV footage of each of these injuries.  These kinds of injuries requiring acute force most likely caused by another player's impact at a high speed (momentum) rather than self-inflicted so I am not sure that the kind of turf will be a big factor. </p>",
