With all due respect longtimefan, yes it is hindsight but almost any fourth down conversion in an intense game is viewed as important. Even during the game it felt like a blow when it happened. Looking at the first replay, it took me two times seeing it to see the ball hit the ground. The second one shown later removed all doubt that it wasn't caught but it was too late.
Yup I agree a completed 4th down play is important, cuz more than likely its a close game, specially when its near the red zone..
But no real evidence that it was not a catch..As someone one?? pointed out, no players (not that I heard of) on the field went nutts that it was trapped..So MM went with what his eyes saw and what his players saw that it was a completed catch
