Al Saunders: was he necessary?

[dmek25]

i agree with thatguy. in the glory years, coach gibbs was the offensive co ordinator, and he trusted pettibone and the boys with the defense. greg williams has proved that he can coach a good defense, so im not sure why this move was made. the latter half of last year, i thought coach gibbs figured our offense out, what plays worked with what personnel, and basically called good games(i.e. the dallas game and the giants game come to mind) it seemed that they were comfortable with him and gibbs with them. i still dont understand why saunders was brought in
