Welcome back to the second half of my conversation with the legendary Ken Dryden. If you’re over 45 then you know that Ken Dryden is the greatest goalie in hockey.

Part 2 of my discussion with Ken Dryden is about his take on Canada 150, head injuries in sports—particularly hockey—and what can be done about it today.
