I wouldn't put too much emphasis on someone getting a positive testimonial from within the game as people praise their mates to the media, its human nature, all of us would.
You could appoint me as head coach of Wire for a bit.
My strategy would be to sign up the senior players on long term expensive contracts, give them a lot of freedom, allow them to go out on the razz and buy them drinks, be their buddy.
Watch what the quotes to the Warrington Guardian are when the team is in trouble...
"Dressing room fully behind Sally Cinnamon" says Wire player, "we all know we have to improve, we have to pull together but Sally is a great coach and we are all 100% behind him"
then after I get sacked
"Some of us need to look at ourselves in the mirror and take responsibility for getting Sally sacked. It was a shock to us all when he told us and we are all devastated that he is leaving".
