I guess that depends on your team. Cowboy fans from 70's would take that version over the free agency era any day. It was great knowing all your favorite players were returning every year. I knew the whole team by number in 1977. "Team" being the operative word. Those were true teams. Todays teams are usually a collection of hired guns selling their services to the highest bidder.
In regard to TV, the churning of rosters every year makes projecting MNF games a complete crapshoot...........which is why MNF usually sucks.
As far as game matchups for the five networks (CBS, NBC, FOX, ESPN, NFL Network) with (almost) exclusive rights for the NFL regular season:
All 32 teams get a game on Thursday Night Football... be it on FOX and / or the NFL Network.
Games for Sunday night on NBC are more selective: Playoff contenders from recent seasons, along with longstanding franchise rivalries get the nod.
The same is in effect for the national - late Sunday afternoon games (4:30 Eastern /3:30 Central time) on both FOX and CBS.
However - the 2021 MNF slate wasn't a crapshoot; it was created to be very unappealing - thus failing to attract viewers.
For this past regular season - division rivalries dominated on MNF - 8 games out of 17.
But why three of them being in the NFC North - Green Bay once- but
Chicago twice?
Lions @ Packers was the week 2 MNF matchup.
Packers 11-1 v. their division 2019 + 2020.
Super Bowl LV participants Buccaneers & Chiefs played one time ONLY - both hosting the game ....
and their opponent was the pathetic Giants.
Bills and Titans were in the AFC Championship Games the two years prior to this postseason.
But both appeared only one time on MNF in 2021 - against each other.
Meanwhile - the Raiders APPEARED TWICE in the first four weeks -
Sept 13th ___Baltimore @ Las Vegas.
Oct 4th___Raiders @ Chargers.
NFL fans have been denigrating the MNF broadcast crew put forth by ESPN for the last decade.
But in my opinion- the dreck slate that the league parcels out to them is THE MAIN ISSUE THAT NEEDS TO BE CORRECTED.
