The straight 4-4-2 didn't even always work when Nedved and Camo were fit and playing, and now some folks want to revert back to it with Brazzo and De Ceglie out there... and expect it to work?
There is no such thing as a formation that always works.
One of the advantages of a straight 4-4-2 is that it is, by far, the easiest formation possible. There are virtually no problems in terms of players being uncertain of what is expected of them & you're always going to have a very balanced squad out there (if you use common sense).
So, it may not be the best possible formation, it may even not be the best suited to us, but out previous games have thought us (or me at least) that only very few people in our team are capable of reading a game in terms of positioning with / without the ball. There seems to be a huge lack of awareness.
(Temporarily) Resorting back to the easiest & most predictable formation possible could very well solve some problems.

Idiots.
Why is it that people have different opinions are always idiots or morons?
Someone says we should bench Diego => gets called a moron.
Someone wants a 442 => idiot
Some other guy wants Melo benched => dumb
