I have to disagree, they haven't really hit form, just eking out wins and seeing it pay off. They'll hit form soon enough although as you say, might still implode. However I think they're good enough for the play-offs and may well be in the Prem next year.
They've been knocking on the door for some seasons already and I think this is the 1 that'll see success.
I may be wrong and you may be right, we'll just have to see. But what's the use of seeing them fail whilst we ourselves don't show any sign of succeeding?
Let their success be a catalyst for us to succeed next season.
