Who could it be?
Tony Franklin might no longer be at Cal ,but the Bears aren't expected to deviate too far away from his teachings. For those thinking that Cal was going to overhaul the offense from what Tony Franklin brought the last three seasons, think again. The new offensive coordinator is likely to be comfortable sticking to the majority of the current principles.
Aside from a few adaptations to parts of the overall scheme (like the movement from the vertical set blocking scheme to the more traditional dropstep techniques), the Bears aren't expected to deviate too far from what's worked the past few seasons.
