This is my point exactly.
If the beings in power truly were out to protect the players, and to enhance the free-flowing, attacking football, they can do something about this. But they have to give the referees the power to do so.
When NHL had a worsening problem with slashing and tripping in the early 2000's, they tweaked the rules, and increased the penalty for this, and lowered the threshold for when to incur the penalty. Football can do this as well, and has done so before, with the "tackle from behind"-change from a while back, and now recently with the "don't talk back to the ref"-change.
It leads to a brief, turbulent period with a lot of cards and some very hypocritical pundits slating the refs, but eventually the game adapts, and you get the change you wanted.
Unfortunately, there are some out there who thinks that kicking the other team off the park is a very valid way to win...
