Just finished the Bills/Jets game. Similar to what we do offensively: lots of Y-stick, dragon (slant-flat). Out of Detroit (2W2TE1B) personnel and this:
the Bills threw dragon out of this 3 times and did PA with 3 verts once.
Dragon/Slant-Flat/D-slant looks like this, courtesy of Mike McCarthy:
Here's what the Bills looked like against the Jets.
It's a concept both the Chiefs and Bills use a lot regardless of formation but if/when this formation pops up on Sunday, there's a decent chance they're throwing to Sammy via Dragon.
