If Teams B and C have to play one of their last two games against each other and Team A holds the tiebreaker against Teams B, C and D, then Team A will have clinched a playoff berth since they cannot be overtaken by both Teams B and C. Also, if Team D does not hold a tiebreaker against any of Teams A, B and C then it will be out of playoff contention since it cannot overtake both Teams B and C.
