I reckon you could look back at this game and you could narrow down a few things that lost them the game. It wasn't things like Huxley dropping the ball a few times or giving away penalties. It was simple strategic decision making. For example, when the Rebels were hot on attack, 10metres out, the forwards had the ball and probably a phase or two away from crossing the try line, except the scum half panics, spreads the ball hugely wide when nothing was on, the man gets isolated and wuala, turn over. Another example is when the Rebels were making good metres and into the Sharks 22, Kingi (another poor decision from the scrum half, albeit a different one) tries to do too much and sends a poor grubber kick down field.
Catching passes can be fixed in a week. Communication and decision making is improving at the Rebels, but clearly as I have identified, there are issues still and these will be slowly ironed out I expect as the season progresses. Good signs overall.
