Well Billy's said "I'm going nowhere." Which I think is the problem, Billy...
Billy won't quit, he'll wait to be sacked (possibly engineering it with a few "I haven't been backed" comments.)
I think part of the problem is that nobody in the Forest, ahem, Camp, went into the playoffs with any confidence. I live in Nottingham and know a fair few fans, and none of them, nor any on forums, had any confidence at all, and I think that spread to the team/management/coaching staff/tealadies. You seemed to go into the playoffs expecting to lose (and I can see why) and lo and behold, you did! And now all that Billy can talk about is luck.
Ah well, I'm really looking forward to next season, still Forest and Leicester to play, plus my friends' teams West Ham and Brighton, and I do wonder if Billy will ever get another team promoted?
