I love proper test cricket as much as the next man but Warner batted beautifully and fully deserved his ton. If Pakistan can't bowl properly it's not his fault. It's a very rare occurance and hardly the death of test cricket. The booing was good natured and in the context of the situation where everyone knew Warner needed a half dozen runs to do something special, I think even Renshaw understood by turning down the odd single so Warner could stay on strike.
I've Not even mentioned Warner. Was merely the discussion against renshaw.
Just because one man is playing quickly/well/to his strengths doesn't mean the other has to risk anything to keep him on strike.
5 days in a test match. Warner didn't need his ton before dinner, getting it after would have been just as spectacular.
Renshaw not risking anything lead to a very fruitful day for himself. And is the correct way to play. This is day 1.
