Sunday afternoon, the Dallas Cowboys led the Detroit Lions 27-3 in the third quarter.
Detroit had just gone three-and-out in their first possession of the second half, when Romo dropped back to pass and found Bobby Carpenter for a quick touchdown pass.
This would be fine, except Bobby Carpenter wasn't the newest Dallas Cowboys tight end—he was the Lions linebacker.
On the next drive, Dallas is now facing 3rd-and-2 from the Lions 48. Romo is in the shotgun formation, takes the snap, then rifles a touchdown pass to Chris Houston.
Normally this would be fine, if Chris Houston was the Cowboys' latest practice-squad call-up at wide receiver. But he isn't—instead, Chris Houston is Detroit's cornerback.
Later on in the fourth quarter with 4:22 remaining as Dallas led 30-27, Romo dropped back to pass on 1st-and-10 from his own 20 and completed it Stephen Tulloch at the Dallas 40.
But not only was Tulloch not the intended receiver (Jason Witten was), but Tulloch isn't even Romo's teammate.
Stafford and the Lions would then march down the field and score what would turn out to be the game-winning touchdown, as the Cowboys completed the biggest choke of Week 4, losing 34-30.
To think that based off of his gutty performances against the 49ers in Week 2 and Washington in Week 3, I actually thought of Romo as an MVP candidate. I was mistaken.
Romo only further solidified his reputation as one of the least clutch players in NFL history.
But who else is on that list?
We'll start with Romo's full resume on the next slide.
