Apologies for the selective quote: Unless you have any inside knowledge, this is:
1. A guess; and
2. An unsupported opinion,
each dressed up as fact. We should know the answer to one of these statements shortly. If your guess proves incorrect, I hope that it's acknowledged to have been a guess. I also hope that the SD is given enough space and time to prove the other statement to be incorrect, because I wish the club to succeed.
For the record, unless the manager is inexperienced, my gut feeling is that the SD role is a luxury that we can't afford, but I will try not to pre-judge and I hope it works out. (As an aside: perhaps the SD role is also a temporary fix to support a less experienced Board while they bed in, regardless of the manager choice?)
