Well heck. The worst has happened. We know that now. The big question is, what next? At this point, more of the same is probably to be expected. If they appear to be playing 20 minutes each game, I expect over the next few games they will ratchet that up to 40, and then 60 minutes. That's where they will start winning some games. At that point we pick up the pieces.
If retaining your sanity is important to you at this point, I recommend this piece written by Jeff Little over on The Cannon.
