Miami having trouble in the red zone is unsurprising, they count on the threat of Tyreek or Waddle taking the top off to keep open all that short wide, or medium middle stuff that Tua can actually throw. But once they get close to the goal line, the defense doesn't need to respect that and can tighten up the short zones and on that last drive you could see the struggles with more bodies in the mix.
Burrow on the other hand, for the "best processor since Brady" doesn't seem to know where his blitz answers are.
