a lapse of committment by our winger to put the ball down properly
Are you serious?
You think he stopped trying somewhere between catching the ball and putting down?
He got lazy between catching the ball and letting gravity take over?
If Hagan thought the failure to ground the ball Grothe would be in reserve grade, probably forever.
I reckon the main reason was that when Hayne caught and passed without looking, it took Grothe fractionally by surprise. He caught the ball further to his right than he would have liked. As such in getting to ground the hold on the ball was not as strong as it would normally be and the hit came at the right angle to force it free.
To say there was a lack of commitment is pretty harsh. Have another look and I'll do the same if I get a chance.
Eela. are you sure JTB hasn't hacked into your computer? LOL
