That actually bears out what I've seen. Which coming from the BBs makes sense. When outmatched, I see players foul more often. If there's a foul, there's a greater chance of injury (due to a greater number of "rolls" in the system)
One thing I don't see though is more aggressive players getting injured more often. Although it's hard to tell precisely how aggressive a player is, I'd wonder if there's a real marked difference between injuries on a player such as:
