I strongly suggest anyone that likes this formation to look at the RnG's version.
It has good running plays:
HBDS - not as effective as the Pats' one.
FB Inside
HB Draw
HB Power O
HB Toss (use once or twice in a game, coupled with some manual motion passes)
It has good passing plays:
Deep Comeback - Cousin of 689 hook, the FB does a delayed route instead of his usual flat
Deep Cross
Mesh
PA Falcon Slide
Slot Post
Slot Seam
WR Cross
WR Spot
HB Slip Screen
IMO, Run 'n' Gun Gun Split Offset is one of the best formations in the game. At least, it's the most balanced one.
