Netflix and AmazonChristmas is on a Thursday next year so i fully expect the NFL to have a 3 game slate to try and further shyt on the nba. If they were smart they would have games on FOX, CBS and NBC (If they're not broadcasting any NBA Christmas games next year.
Hell honestly, i would try and do a 4 game Christmas day slate and the NBA did a 6 game slate.
Imagine if this was the NBA/NFL Christmas day slate next year. (Based on next years NFL Schedules)
9:00 AM - ABC - Packers at Steelers
9:30 AM - NBC - Pacers at Knicks
12:00 - ABC - Cavs at Bucks
12:30 - CBS - Lions at Ravens
2:30 - ABC - Mavs at Celtics
3:30 - FOX - Kansas City at Dallas
5:00 - ABC - Lakers at Warriors
7:00 - NBC - Bengals at Bills
8:00 - ABC - Houston at Minnesota
10:00 - NBC - Suns at Denver
10:30 - Rams at 49ers
Tell me who says no to this?

The numbers for the NFL are in.
As anyone would have reasonably expected, both games finished about five million viewers shy of last year’s equivalent Christmas Day windows. As has been the case with games on Peacock and Amazon, Netflix attracted a younger audience than is typical for an NFL game, with Ravens-Texans delivering the league’s largest Christmas Day audience on record among adults under 35 (dating back to 2001).
While Netflix cooks the books and viewership declined. Streaming clearly attracts a younger crowd which the NFL will probably like and being on a streaming apps has its advantages @K-Apps you are right FOX or CBS might be trouble in a few years.
