'"With Trubisky, the system will be especially crucial," said Benoit. "He is a better out-of-pocket talent than Cousins, but he still must be an offense's cog instead of its fulcrum. The complicating factor is that Trubisky is utterly inexperienced playing from under center; every snap he took at North Carolina was from shotgun. In today's NFL, about 60 percent of snaps are from shotgun. But teams whose systems tend to incorporate a quarterback rather than feature one do so by building their passing game off their running game. Which means their quarterback must play from under center."'
