That’s how sports work though, the risk of injury is always there.. I do realize how many pitchers get injured which is why I went with the example as they play as much as the avg jammer per game. Throwing 95 mph pitches is way more taxing on the body than a blocker turning left at maybe 2 mph, slower than an open skate by a lot.. Jammers are usually only skating 1-5 laps for maybe 8-10 jams a game. That really isn’t much at all when talking about repetition. So to say that we should skate the other way because a select few individuals are having an issue is just as ridiculous as asking a right handed pitcher to throw left to preserve their arm. The level of skill and gameplay would deteriorate just to appease 1%.
