I totally agree.
However I am not going to say it is ALL Mike Sherman's fault. Yes he was the GM, but you have to remember he was also the HC. After a while, when it became apparent that Mike could lead this team to a winning record, he should have been relieved of his GM duties and someone in house that Sherman was comfortable working with should have gotten the job. ONE THING TO REMEMBER THOUGH: HINDSIGHT MAKES THINGS LOOK SO MUCH MORE SIMPLER THAN THEY REALLY ARE.
While Harlan should have stepped in on this, because Sherman was clearly exhausted doing both jobs, I think it can be understood why Harlan let things continue the way they were. When you look at it, the Packers were only one playmaker away from really being a threat, and Sherman's draft strategy reflected that. He was constantly moving up to get players with outstanding physical skills and great athletes (but not necessarily the best football players) in hopes of finding that one special talent to get the Packers over the hump. At least he attempted to get the Packers over the hump.
Also a part of the blame must go to the scouting staff, specially to the person(s) that Mike Sherman relied on for most of their info. They are in part responsible for the terrible scouting and subsequent drafting that occurred.
Sherman does deserve the majority of the blame, but it isn't all his fault.
