how deep are you thinking when you refer to taking chances down the field?
The offensive philosphy of the Gillman-Coryell offense is to pull the safety's either out towards the sidelines or deep covering the outside deep WR.
Generally what the offense wants to happen is for the safety's to move onto the deep WR's leaving the TE, Slot Receiver, ext open for routes over the middle of the field in single coverage / gaping holes in a zone based defense.
So to answer that question, it would depend on what the defense is running and how they are playing their safety's. Typically I'd say those 5-10 shots down the field would need to be 25+ yards on average.
Those passes don't necessarily have to be completions, just the shots need to be taken. The offense will be more effective if 2-5 can be completed, the rest is based off of running the ball and YAC from crossing, out, and slant routes.
While it's probably a given that the Panther's will run the ball more and rely on Play action passes. "Probably similar to what SD ran in River's rookie season play calling wise" the key is still to push the ball down the field on those passes.
So either way Carolina runs Chud's offense, the QB is going to need to be able to complete those Down the field passes. That and the fact that Chud is throwing in option plays and runs for Newton, makes me think that Newton is likely to be the starter come opening day. "That is unless he completely bombs in the pre-season games, maybe the first one won't be pretty. After that I think he settles down and becomes the starter for the season.
Way too many things being added to the offense for Newton + the offense style being suited more so for Newton then Clausen = makes me think that the decision has already been made on who's the starter for the season.
