Me thinks some people got spoiled by Mr. Newton.
Cam took over games which is why I say Gus got out of the way and let him play. Six new QBs in 6 years for Gus. He's never used a 2 QB system but he has admitted that his handling of the QBs this season has disrupted their rythym.
The NH offense that Cam ran was geared for his style of play with more run option. (ISO and draws) This style would seem to suit Frazier better. IMO, Chris Todd could not run this (geared for Cam) offense effectively, especially with this offensive line. And I think Mosley and the entire team would benefit more from the style and play selection similar to that of Todd's SR. year.
There is a stark difference in the style of offensive play then and now. Maybe it's how the plays were packaged, but it's different and it shows in the lack of offensive production.
I think it hurts a QBs confidence to keep shuttling him in and out with another. The line play has been very inconsistent but I think our overall play would improve with one QB, or at least several series of one QB without a change...no tutor required.
