Defensive formation on 3rd and 16 in Eagles game.

And yet it would have been successful had Harris and Lattimore not collided or had Howden properly come up and made the tackle.
Disagree. The trail defender would still have been trailing and the TE had the angle to the sideline on the Safety. It may not have been the huge play it was, but they still more than likely get the first easy. Like I said. The play call is fine if not for the situation and personnel. 4 back at the sticks. Force the quick throw. Come up and make the tackle. Force the 4th down. We do it all the time.
