You have a 7 point lead at home, the ball and a 3rd and 7 when Kupp is emulating Calvin Johnson. Your defense is 100% totally gassed and has been getting pushed around all day.
The offense did not do its job at that point. The offenses job was to go for 7 yards to put the game away, not play to have the other side burn a timeout. There is no mathematical equation where the better choice was to give the other team life just to make them burn a timeout vs. just trying to end it right then, right there. So what, they cost Jimmy GQ the ability to spike the ball 1 time. Yeah that worked out real well when they had been moving the ball at will against the team for half the game.
Then at the end of the game, you've got a timeout left, 20 seconds on the clock, Stafford gets sacked and you need 30 some yards to get into field goal range. You've had him throwing the ball deep all game as it was, so what do you do? Well, apparently you don't call the timeout and take a shot. You go to OT where you have a 25% chance of winning.
