You're describing 'me', @sneakypete ROKU my ass!
Why in the world do I need this 'stick'...that 'stick' when it ain't the damned LIVE forecasts such as my local news stations from 4AM to 9AM?
Yes...(lowering my gaze)
, I still pay VERIZON FIOS $220. monthly for something called GIG SPEED internet (it STILL buffers, the dirty SOBs), and every channel from 2 to the music channels at 1400+.
And, uh... I don't watch any of them. Why do I need to watch Denzel and Meryl' MANCHURIAN CANDIDATE another dozen times?
Can you get the 'LIVE' NFL playoff games on ROKU? NO. You can't.
Like Vinny Barbarino.... "I'M SO CONFUSED!!"
There is a trick for that.
Get yourself a smartphone (if you have an old one that you stopped using, all the better), the official NFL app... and one of these doohickeys.
The cardboard model (you can usually find one of these for quite a bit cheaper than Amazon if you hunt online a bit):

https://www.newegg.com/p/0FC-011Z-00002?item=9SIAJ7WGWJ4876You basically get yourself a dark room, link to your soundbar or speaker by Bluetooth, turn the smartphone's brightness to the highest it goes, turn on the NFL game of choice, put it into the projector, and point it at a wall. Adjust the focus, and badabing—you have a decent, TV-sized image coming from your phone.
This is, without exaggeration, the main way I've been watching the NFL for most of the past year. Is it perfect? No. But in the absence of a good antenna signal, it's worked pretty well for me.
(If you're in a metro area, I would strongly recommend an antenna, which will give you your NFL games and local forecasts live for free—or at least, only the cost of the antenna and the TV set to which you hook it.)
