Then you should've read what I wrote, dear friend.
I stated that the defense was good for the first 70 minutes of the game. Didn't say anything about the preceding games. I just merely pointed out that they are capable of performing but have been let down by lapses of concentration - most pointedly immediately following the 70 minutes I specified.
With regards to specific fixes to those issues, I'll leave that to the experts on this board.
But don't quote statistics from all the other games and minutes that I did not include in my assertion in order to disprove that assertion. It's simply not logical.
