Obviously the 29-30 rule changes changed things. I've discussed playmaking centers in the past. But, one thing struck me. Prior to 29-30, there were stay at home d-men like Ching Johnson and there were rushing d-men like Shore and Clancy. The ruashing d-men were very effective goal scorers. Modern defense includes activating the offense with breakout passes, this wasn't possible until after 29-30. So, what I'm wondering is, who was the first defenseman to really use the breakout pass?
