"I've really lowered my target area to where it's down around the knees," Harrison said Friday on ESPN Radio. "Situations come along where you could tackle the guy high. I don't do that anymore. I tackle the guy low."
Harrison points out that hitting low doesn't necessarily make the game any safer. In some ways, Harrison believes this approach is equally dangerous. The four-time Pro Bowl selection recalled his hit that injured Denver Broncos wide receiver Eric Decker in a playoff game last January.
"I could have tackled him high, but if I had hit him high, I probably would have gotten a helmet-to-helmet or something and gotten fined," Harrison said. "So I hit him low and (he) strained his MCL.
"They're saying it's a life-threatening injury to hit a guy in the head and he gets a concussion and so on and so forth, but I think a life-threatening injury is to go low on a guy and blow out his ACL or whatever, and he's not able to come back the way he was before. Now he can't make a living, he can't feed his family, he can't do what he does. That's life-threatening to me."
