Sure, in a lot of cases yes. But I'm saying the game changed because the rules changed. Like, in the NFL, you'd see guys getting injured because they tackled awkwardly and so the horse collar penalty was added. That changed the way defenses tackled. Same with the NBA. Saw players getting lower leg injuries because defenders often would sneak a foot or crowd him enough that he can't come down on his feet, and the NBA made that a foul. This gave shooters a bit more space and opened things up for the offenses.
