Those are soft tissues too but I think it's unrealistic to prevent all muscle, ligament and cartilage injuries in football. I've only seen Wintrich quoted as listing quads, hammies and groins injuries as prevented. Would "zero muscle strains/ tears" be more accurate? Ligaments and cartilage would mean no ankle sprains, knee sprains, ACLs, cartilage would be labrums, meniscus. If he could do all that he wouldn't be at BYU he would be in the NFL. I love Wintrich though, very glad we have him.
