I was thinking the same for some time, but then when they beat Huddersfield and Palace in successive matches I changed my mind and thought they'd be alright. I still did until Saturday, but to lose in that manner to a side as out of form as Bournemouth were had the potential to be devastating for them.
Your comparison with what happened to us after that 6-0 at Preston is a good one and I firmly believe the opportunity is there for us now because Brighton have a real downward momentum about them - in it's way, losing to us will be more shattering for them than the Bournemouth game was.
