In truth, not much.
So the Lions can thrash a scratch team who have been on the lash for the last fortnight. So what, so did a reserve England team last week.
Today's match wasn't really about rugby. It was about money. Why else would the Lions agree to play a match in such ludicrously hot and humid conditions? As a warm up for the main event down under it served little purpose, but no doubt someone's coffers are now suitably full.
