I honestly don't think defence is our problem, the table alone shows we have the lowest points against in the division. Sure some aren't as good at tackling as others and they may be targetted, just as some are faster, some are stronger, some are better passes etc. I lost count at the number if sets London had in our 20 in the second half and only managed to squeeze over a couple of times after very long periods of being shut out. Our defence was snaffling most of it out but eventually a ball drops or a tackle is missed, it's just stats.
The problem is why they were allowed to be there so often, and that comes down to us not respecting the balls when we have it. It's a cliche but true; the best way to stop the opposition attacking your line is to not let them have the ball, we coughed it up too easily. Then after we have dropped it a few times we clam up and the creativity goes and the situation worsens.
Thought the guys returning from injuries put in good stints, particularly Douglas who I'd have been tempted to give MoM
