I'm with Scorpion, as good as the team has been at climbing back from deficits, we've failed on critical comeback drives as often as we've succeeded. In these huge moments, our coaches and best players have let us down when we needed them the most. Also, our kicker sucks.
If we look just at the closing moments of all our losses, regardless of what went on before (blown coverages, picks, missed kicks, etc), it comes down to:
Green Bay: Defense lets Rodgers lead a 6+ minute drive to kill the clock when if we got the ball back we were down one score. Could have conceivably come back to tie, but it was unlikely.
Tennessee: Offense turns it over on downs mid-way through the fourth and the Titans run off enough clock to force us to an onside kick and we lose. Could have won, but we got punched in the mouth at full strength. It was really hot.
Washington: Defense blows it to allow a late TD. Russell Wilson takes a huge sack and has to throw a hail mary to have any shot. Could easily have won in the waning moments despite the disaster of a game that preceded them.
Atlanta: Awful clock management by Pete early in the game combines with bad clock decisions by Russ and of course Walsh misses the game-tying FG.
Jacksonville: The offensive series above combined with the defense letting the Jags pick up a 3rd and 11 on the ground. Could have won this game.
We had great shots to win three of those games and could have done it in the first two. Hurts, but great to see the team in every game. Now, conversely, we could have lost in some of our wins.
Houston: BoB goes conservative and we stop them on three straight runs to give Russ the ball back after he threw a devastating pick.
LA: Cooper Cupp commits a tough drop that would've given the Rams a one point lead.
Niners: miracle TD by Russ to win it by three points
Cards: the double pirouette by Russ to Doug to setup the TD that puts the game out of reach for the Cards
Giants, Eagles, and Colts games weren't that close.
