Multiple change of possession - with foul

[Robert Goodman]

All A's recovery did was assure that team B would not accept the result of the play -- which they might've if B recovered and wound up in a better spot. But you'd better give them the choice, because if A's recovery left them in a bad enough spot, even though with a new series, a defensive-minded team might prefer that. So neither B's fumble nor the play following it can be ignored.
