Hockey has changed over the past 4 decades

Once in a while I flip on a classic NHL game to capture a glimpse of a game that no longer exists. The clip below is a 1967 game between Toronto and Chicago. The game seems so much slower than today. The players are smaller and so is the equipment, particularly that of the goalies. Of course with less equipment you don't see the devastating hits that you see today. What you saw were hip checks which if you watch long enough you will see one delivered by Bobby Baun who was one of the best at throwing hip checks. None of the players in this clip would be able to compete with today's players except perhaps Bobby Hull. He scores a hat trick against the Leafs.
