Putting alot of weight on these sack numbers is misleading. A QB does not need to have good pass protection to have low sack numbers. Quick slants, fades, quick outs all lend themselves to low sack numbers. Some QB's tend to hold onto the ball to long and take a sack because they are unwilling to throw the ball away, Marino was among the best best at tossing it away to avoid a sack, Others do not step up into the pocket, fell the pressure, see the passing lanes, ETC. I find it hard to believe Bradys sacks per attempt when you think about how fast the ball is out of his had most of the time. Jay feels the rush ok, not great but ok, but does on step up in the pocket as well as I would like to see. It also seems to me that he likes to scramble to his left to avoid the rush but he does not throw well when moving that direction. IMO I think that those numbers are more of a hint as to not only how long the QB has to deliever the ball but also how well the rec are getting seperation and how well the QB is doing at getting the ball out on time. If I were to look at the detroit numbers I would lean more in the direction of a QB that was rushing the ball out and was a little unwilling to setup in the pocket and take a hit to give his rec time to finish the route before unloading the ball. Bledsoe is an example the other direction, Drew has tended over the last few years to hang onto the ball to long and be late on alot of his throws. Anyway those numbers really dont tell anyone much about what is going on in the larger picture.
