I disagree with the boo birds, in particular, one RINO-loving radio commentator who said Carroll made the stupidest play call in the history of the NFL. What if Carroll had kept the ball on the ground and Lynch had been held for no gain on successive plays until the clock ran out? Would that have been smarter?
In my decades of watching football--high school, Division 3, Division 1A and pro--I've seen many a successful goal line stand.
Throw the ball to a place where there are really only three possible outcomes: (1) the receiver catches the ball for a TD, (2) the receiver catches the ball out of bounds, or (3) the ball is out of everyone's reach and falls incomplete.
None of these outcomes ends the game for the offense.
