Its known that Saban has run a zone D for the most of his coaching carreer and zone blitzes are one of the most scary thoughts for some QBs, think they are throwing the house on you cause you see Safeties and LBs Blitzing try to throw some quick route before they get to you and bam there is a DE like Jason Taylor standing right in beetwen you and your WR. We all know that Pooles biggest knock its speed which its not all that important in zone schemes, we also know that Madison has lost a step but has great awereness and instincts and we also know that Reggie Howard thrived in Carolinas Zone scheme and fell flat on his face in Miamis man cover. All this is to point that Surtains biggest strength is man coverage while all the other guys are better suited for zone that is leading us to beleive that Surtain its actaully expendable, not that we wont miss him but that we will be able to move on after his departure.
