I think its entirely within logic to not expect to win, but expect a level of commitment and performance, no?
In business - my area of experience - I've seen teams both improve and worsen in quite short order. I know nothing about what happens at Wasps - I have no axe to grind - but like financial instruments, past performance is no guarantee of future performance and leaders often, through no specific fault, sometime get to the end of their journey - presumably, ditto for players.
Having entrenched positions are not informative, but I don't think it illogical to consider a wide range of issues that might be a problem.
Again - its only a view from the stands - but its certainly not the same feel of the team as it was - and that's as likely down to the changes (past and future) in personnel (players) as anything else.
However, we've gone from looking like everyone wants to play for the team to looking like everyone just wants to get to their summer hols in one piece. We've been v unlucky with injuries, call ups and everything, but that doesn't for me, explain everything
But I'll happily admit I know little of the realities of being a rugby pro these days
