This again is not what he said. Hopper said after playing on when he thought the discomfort was from the knee bandage he still felt discomfort so he took himself off.He first injures and grabs at the hammy at the 12 minute 8 second remaining mark of the 3rd quarter, motions at the bench by stretching his knee out but then continues to play for another 2 minutes before aggravating it further (the bit where Oliver consoles him with a pat on the head)
There is no evidence that he aggravated it further and no one has said that.
I am not defending our injury record but I think if we are going to attack it then it should be based on facts.
Whether the injury itself was caused by him coming back a week early is what we should be looking at.
