Yes and no.
Game plan certainly limited the occasion for mistakes and didn't trust Santino at all until we had too.
And
The two things that I saw that helped win the game that seem singular to Santino of our 3 quarterbacks: 1) Ball security in the pocket. While Kern's fumbles were both the fault of horrendously missed blocks by the RBs, Santino's size and the way he carries the ball in the pocket led to 0 fumbles (and while there were fewer total plow up sacks, he still has some folks in his face immediately on occasion), and 2) Breaking the pocket. Santino was quick to abandon the pocket and roll out, limiting sacks. While it didn't often turn into a positive play, it generally resulted in a less negative play (I'll take Santino scrambling and going out of bounds for a 1 yard loss over a 4-7 yard sack or panicked throw that gets picked off).
