It's an indicator, for sure.
Look, I'm not pro-Clough or anti-Clough, I just look at that list and I don't see anybody who particularly stands out above Clough. Slightly better, slightly worse maybe.
Adkins did an excellent job at Southampton and a terrible job at Reading. That's a gamble. I guess he has League 1 success with the biggest side in the division so possibly is the stand out option. I'd not be against it but the Reading debacle would ring alarm bells for me.
Ferguson is a proven failure in League 1 with big budgets - Peterborough. Did he manage PNE in League 1 or was he in the Championship with them? Either way, not the answer.
Everybody wants Clough out because of his defensive minded football. Guess why Sunderland fans wanted Poyet out?
I think Adkins is an option but a gamble - has he still got what he had five years ago? Redfearn could be worth exploring. Deane is the intriguing one. However, it's a massive massive massive gamble and a massive decision to make.
