What you say is true, but I would still disagree with the overall assessment. To put it bluntly, it is the pilot's job to be thrown into unexpected situations. Modern airliners mostly fly themselves, and the pilots are there to a) coordinate with ATC b) step in when the shit hits the fan, which does happen with some regularity. Ultimately this accident was caused by a confluence of many factors, as is often the case, but my read on the situation is that a competent pilot should have been able to handle this emergency without any losses.
