Just some old articles saying how important a Center is in a Manning Offense.
But essential to his success is a smart center, since centers are generally responsible for calling out protection schemes at the line. Unusually, Manning often changes the protection schemes himself, meaning he will need a center who can keep up with his football mind.
These past few years in Indianapolis, Jeff Saturday anchored that line, we should expect the center to be the foundation once again here in Denver. With a strong center it begins to form the inside room of that pocket that Manning loves. A center who doesn't shift and can hold his ground will allow Manning to step up knowing that he's protected up front.
Now in terms of pre-call, the center is incredible key since they help recognize the defensive front and communicate this around the offense.
