here's a scenario where they win 8 in a row
We aren't winning 8 in a row, but if they did they'd almost assuredly make the playoffs. A scenario like you developed (where every playoff team in a conference had at LEAST 11 wins) has never happened since the league went to the new playoff format (2020). In either conference.
Also going back to 2002 when the league split the divisions into 4 teams, it's never happened.
In general, it's extremely rare for a team that wins 11 or more games to NOT make the playoffs.
