Players can get injured on the 1st play of the game. Players can get injured on the last play of the game.
If you're going to base playing time and situations on the risk of injury, then let's be honest - the only absolutely sure, 100% way to avoid injury is not to play. Every time a player steps foot on the field, there is a chance of injury. Granted, some plays and situations have a higher risk of injury. But, the play on which Smith was injured was a completely routine play - one the Gophers run 40 to 50 times a game. Do you not run that play because there is a 1 in 20 or 1 in 30 or 1 in 40 chance of an injury?
when you play football, players are going to get injured.
In SW MN, a week ago Friday, in a 9-man game, a kid came up to make a tackle. everyone who saw the play said it was a completely routine play. the kid's head hit the runner's thigh. And he broke two vertebrae in his neck. He's in the hospital with paralysis from his mid-chest down. The only way to prevent that injury is not to play - or go to flag football.
