Blackpool for me, they are just running in to form and there are several Northwestern sides in the relegation battle.
Unfortunately I think West Ham have the extra quality required, though I'd love to see the look on fat Sam's face if they messed it up. The 4 playoff sides and boro all have players I wouldn't mind pinching shuld they fail, so its all good.
I don't even want to think about the play-offs until after Saturday. But assuming we're not in them, I'd say Birmingham have the best manager, West Ham have the best squad, but Cardiff, having been here before, and having suffered a Cup hangover, might just be coming back to form at the right time.
