Tuesday Trivia: Blowing Leads, Revisited

Until 2011, the Cowboys had never blown a 14-point lead in the fourth quarter. That streak came to an end when Dallas lost to the Jets in week 1.

Until last weekend, the worst lead the Cowboys had ever surrendered was 21 points. That came against the Redskins on November 28, 1965. Dallas was 4-6 and looking to take second place in the Eastern Division. The Cowboys led 21-0 in the first half and 24-6 in the third quarter. However, Washington went on drives of 75, 64 and 80 in the fourth quarter to pull out a 34-30 win, dropping the Cowboys’ record to 4-7.

The good news: Dallas rebounded, winning its final three games to finish at .500.

Anyway, here is today’s question:

The Cowboys led the Lions 20-3 at the half. This marked the 63rd time in franchise history that Dallas has led a game by at least 17 at the half. Dallas has won 61 of those games.

One loss was to the Lions last Sunday. Against which team and in which year did the Cowboys suffer the other loss?
