I was about to post almost the same thing, our problems defensively lie almost purely down to concentration - as someone else pointed out earlier we concede quite frequently moments after scoring. Likewise one or more players may switch off to allow opponents the opportunity to get uncontested crosses in.
I'd love to see if there is any stats out there of crosses Vs goals scored, as I think we must actually allow more crosses per game to get into the box than the average for the division but concede fewer goals from crosses per game than the division.
I don't believe Rudd was at fault for either of the goals today in terms of whether he should have come to collect. There were about 4 players between him and Crouch for the second and the first was crossed to the penalty spot.
