Sometimes a simple change in the manner in which a matter is discussed tidies things up wonderfully. The discussion here of Bill requires only reasonable attention to tense. Watch:
1) Bill was a great coach for many years, a thing worthy of celebration and admiration.
2) Bill is a failing head coach and a failed GM, facts worthy of his being relieved of his GM job and afforded at most one more year to show what he can do as HC once he is relieved of the burdens of being GM. That is the best the team can offer in the circumstances. I fully understand this is an offer Bill is likely to decline: so it goes. We must be prepared to move on, an approach, it must be said, which offers, as any clean sweep does, very significant advantages over retaining Bill in any capacity.
