It doesn't pass the common sense test.... Nonetheless, if simple wrist shots were traveling (at any point) in access of 100mph, goaltenders would've been maimed or killed in 1968 equipment. Not to mention scientifically there's no possible way a human being can shoot a puck 96mph on a backhand.
No thats for sure. Doesnt add-up, make sense. Id hazard to guess most wrist shots back then, anywhere from 40-65mph+. Maybe the odd one 70+. Slapshots from 75 to the 90's, maybe Hull around 99-100, few others.... as for the equipment, great strides were made from the early 60's on in that regard, but a lot of guys insisted on using antiquated belly pads, essentially little more than quilted cotton arm pads. Companies like Cooper-Weekes that became Cooper etc were in fact producing excellent equipment and you did face some insane Slapshots thanks to the Banana Blade, the puck in flight defying the laws of normal trajectories, arcing wildly left or right, dipping or rising. A lot of the shots high.
But generally speaking depending on what you had, quite confident in its ability to protect, on a deflection or ricocheting puck moving at 100mph. Back then you made a "save", you had it telegraphed. Not like todays goalies whereby its all "block", little consideration given to rebounds or rebound control. Their facing composite sticks, which even in the grip of someone with cement hands can get off one Hell of a shot, far quicker release time, faster, heavier shots. Combined with the cycle game & system play, the equipment advances and almost exclusive Butterfly made in reaction to those innovations out front.
Lots of the older goalies who still play recreationally into their 40's, 60's etc, they'll maybe once a year go retro just for a lark, donning the old Waffle Blocker, GM12 Catcher, old school Cooper GP or D&R pads, Plante mask or whatever. And even at that in facing like-minded older rec players equipped with Composite Sticks, can be deadly. Todays shots using those sticks almost always "heavy". Back in the day youd face hard shots, same speeds, just not all heavy so what we had actually quite sufficient. The pads were heavier, got heavier through a game if you were a major flopper rather than stand-up, but more than adequate and really quite excellent. Couldnt use them effectively, efficiently with todays BF though, pads completely re-designed. Blockers a lot thicker, the side panels actually employed on deflections their that thick; todays trappers, how these guys position it face forward and in closer to the body, the way its constructed, completely alien.
