Its possible, but I would think that would be a bit high.
$40M per team would equate to roughly a $1.3B league-wide annual revenue increase. Its possible that with an increase from 47-48.5% revenue share, it could climb that high, but that seems overly optimistic.
In particular, the league is actively looking to replace AT&T as their exclusive provider of NFL Sunday ticket, and are likely looking to partner with a streaming platform for that service. Consensus from what I'm reading is that, even if they stretch that out over multiple platforms, they may struggle to get the $1.5B price tag that AT&T has been paying. Thought process is the new consumer model may drive to more "local purchasing" with those platforms, as users have started drifting away from paying hundreds of dollars per season for a full slate of games, when most users using the package are only seeking a handful of games per season (non-local viewership).
