When Saints fans yell "Who Dat" on Sunday, they might just hear a rival answer from a big portion of the crowd at the Mercedes-Benz Superdome.

The breakdown of Saints and Cowboys fans for the highly anticipated Sunday Night Football showdown could land close to 50/50, according to forecast projections compiled by VividSeats.

The company's forecasts, which have accurately pointed to road invasions for other NFL and college matchups, are based on data and projections that measure sales trends and other data points. One of those points is location.

Data compiled from other sources indicates the total resold tickets to this point -- more than 15,000 -- suggests a significant, but lower number of out-of-area fans purchasing tickets. That total is culled from secondary market sources including the NFL Ticket Exchange, StubHub and Seatgeek, the latter being the official ticketing partner of both the Saints and Cowboys.

Among the forecasted projections was the Cowboys-Rams playoff game last year, where Dallas fans were estimated to make up more than 30 percent of the crowd.

"Cowboys fans are everywhere," said VividSeats Digital Content Marketing Manager Stephen Spiewak. "And they travel."

The totals could skew back toward the Saints' side as fans snatch up last-minute tickets, he said, but a glance back at a "Georgia takeover" game at LSU last season shows what it can look like when a rabid fan base descends upon road games.

"Not apples to apples, but [it's] not unheard of for passionate fan bases to want to take a road trip to Louisiana," he said.

It's the second time in as many seasons the Saints and Cowboys will face off, with Dallas winning 13-10 in Arlington last year and ending New Orleans' 10-game win streak. But Sunday will mark the Cowboys' first visit to the Superdome since 2015.

Reports and images from that game show much of what could be expected in 2019: A huge crowd, littered with blue, white and star logos.

The Saints box office is sold out for the game, but thousands of tickets remain among reselling sites -- with the game's average ticket price among the NFL's highest for Week 4.

The average price had fallen from earlier in the week, down from $471 to $345, but the low-end of tickets were holding steady in the range of $173.

The game is tracking as the priciest home game of the season for the Saints, despite thumb surgery that will keep Drew Brees out of the action.

The Saints' longtime quarterback was absent last week as backup Teddy Bridgewater led the Saints to a victory against the Seahawks. Brees is expected to be on the sideline this time around, Sean Payton said this week, and he'll likely be wearing a headset to aid the offense as it seeks to hand the Cowboys their first loss of the year.
