In order for the Green Bay Packers to win this past Sunday vs. the New Orleans Saints, they needed to play fundamentally sound on defense. And while the Packers forced Drew Brees throw two interceptions in the first half, missed tackles and being on the field for too long caused the Packers defense to falter in end.

But another issue that won't be talked about a lot is the substitution issues during the game. According to Pete Dougherty of PackersNews.com, there were a few times the Packers defense only had 10 men on the field. Here's what Dougherty had to say about the substitution issues.

Coordinator Dom Capers’ defense changed personnel a lot Sunday, and that included botching substitutions that left the Packers with only 10 players on the field a couple times. One might even have cost a touchdown. The first time they had the issue, on a third-and-two in the first quarter, the sidelines called time out before the ball was snapped. But the second time, early in the second quarter on a third down from the 12, no one stopped the play. The Packers had two defensive players run off the field to defend a short-yardage play (third-and-one) but only one ran on. Saints running back Mark Ingram then bounced his run outside left end and had a clear path to the end zone for a 12-yard touchdown that tied the game, 7-7.

We'll likely hear from Capers on why this happened more than once, but when facing an offense an offense like the Saints, having only 10 players on the field can cause a number of issues. That will be one of the many things the Packers will work on before they face the Detroit Lions on Nov. 6.
