Defensive formation on 3rd and 16 in Eagles game.

Maybe, but the only way it goes for a 60 yard gain is the D plays man coverage and the TE's defender gets picked off by a WR or another defender.
It wasn't straight up man coverage. There were 2 safeties deep. Problem was the near side deep safety screwed up and took a terrible angle rather than cheat towards the sideline. He screwed up. Rookie mistake. Hopefully he learns from it and won't happen again.
