I must not get what the job of the referee is. I was always under the assumption that a ref was there to protect the NBA's multi million dollar investments. Yet in the same game, two players got hurt on complete non basketball plays.
If the refs in game 4 had done their job, Crowder doesn't get hurt, JR doesn't get suspended, and Love doesn't get hurt. Injuries in sports happen, but generally not on non basketball plays. If a guy blows his knee on a dunk, nobody is at fault. If a guy wrecks his shoulder because another player put him in an arm bar, it's not the players fault, it's the refs.
