I think the lesson I learned is "wait and see" after Russell Wilson at Seattle. The read option was fun to watch, but it also highlighted his shortcomings as a qb: he really isn't good in the pocket. I wouldn't quite put the LOB at the top because their pass rush wasn't say the mid-80s Bears. If anything I thought it was Pete's eye for athleticism. They had some of the best athletes I've seen. I think it was mostly Pete, LOB, and Beast. 3-4 years straight as the #1 defense, and the last year were #2 or 3. Personal favorite was the crazy NFC Championship where Wilson was abysmal vs GB. There were a handful of things that had to go wrong for GB to lose, and did.....
Overaggressive corner that led to the fake FG TD.
4th & 1 at the 1 and McCarthy opting a FG
Fourth INT and the DB took a knee instead of running what looked like about 20 yds downfield.
Not having a hands specialist on Seattle's onside kick
Wilson scrambling backwards on the 2 pt conversion and throwing it up to the other side of the end zone and completing it.
Some real head scratchers there. I think that was when I lost a lot of regard for McCarthy when he said to the press points were hard to come by on 4th &1. Wilson and 99 yds to go. It's a no-brainer.
A shame it never turned into a dynasty, but Seattle's athleticism, especially defensively, is what I remember most.
