I wanted to actually see how successful our two-QB formations had been relative to the average yards per play in each game they've been used. A cursory look and this is what I found:
Fritz: 7.0 ypp vs. 7.9 ypp for the game
Denard Jet: 5 ypp vs. 6.9 ypp for the game
Denard Jet: 9.3 ypp vs. 3.7 ypp for the game
So in general, it actually hasn't actually been as successful as I thought. Although, today the packages were very successful aside from the INT.
