Agreed. The 70's Packers (which I thankfully was blissfully unaware of) were the result of continued fuck-ups, and fuck-ups cleaning up the initial fuck-ups, of near Cleveland Brown's proportions.
The bigger issue is taking that shot, and missing, which is a much more frequent occurence...ask the Eagle's 'Dream Team'about that, and there are many more examples, many coming out of Washington and Dallas. I think Elway was more lucky than good, and had a few key pieces fall his way.
