How was this not targeting?

I don't understand how this is not targeting. Everyone is talking about the hit, but I've heard no one bring up this blatant targeting. As much as I hate the rule, I thought this was the kind of hit they are trying to eliminate. If they call this, Michigan State starts pretty far back and probably doesn't win the game. I've seen hits in the grey area being called and discussed as targeting, but why not this one? It's a defenseless player and the Michigan State player launches himself into the head of Baylor's kicker.
