I think this maybe overstates things a bit. But I've been thinking about this. If the imaginary line is, say, as close as the Chiefs thought they got this year, how many of these seasons really slipped away? If we are being honest with ourselves, it is probably only four:There is literally 1 season in the entire BB/TB12 run where there's no way we could have won it all.
2017, 2011, 2007 (All SB losses that all could have easily been won)
2006 (The two best teams in football playing for coronation rites two weeks later. Blown game, etc.)
The rest, for one reason or another, are just seasons. It is these four that stick with me.
